-Material design: [Buttons](https://www.google.com/design/spec/components/buttons.html)
-
-`paper-button` is a button. When the user touches the button, a ripple effect emanates
-from the point of contact. It may be flat or raised. A raised button is styled with a
-shadow.
-
-Example:
-
-    <paper-button>Flat button</paper-button>
-    <paper-button raised>Raised button</paper-button>
-    <paper-button noink>No ripple effect</paper-button>
-    <paper-button toggles>Toggle-able button</paper-button>
-
-A button that has `toggles` true will remain `active` after being clicked (and
-will have an `active` attribute set). For more information, see the `Polymer.IronButtonState`
-behavior.
-
-You may use custom DOM in the button body to create a variety of buttons. For example, to
-create a button with an icon and some text:
-
-    <paper-button>
-      <iron-icon icon="favorite"></iron-icon>
-      custom button content
-    </paper-button>
-
-To use `paper-button` as a link, wrap it in an anchor tag. Since `paper-button` will already
-receive focus, you may want to prevent the anchor tag from receiving focus as well by setting
-its tabindex to -1.
-
-    <a href="https://www.polymer-project.org/" tabindex="-1">
-      <paper-button raised>Polymer Project</paper-button>
-    </a>
-
-### Styling
-
-Style the button with CSS as you would a normal DOM element.
-
-    paper-button.fancy {
-      background: green;
-      color: yellow;
-    }
-
-    paper-button.fancy:hover {
-      background: lime;
-    }
-
-    paper-button[disabled],
-    paper-button[toggles][active] {
-      background: red;
-    }
-
-By default, the ripple is the same color as the foreground at 25% opacity. You may
-customize the color using the `--paper-button-ink-color` custom property.
-
-The following custom properties and mixins are also available for styling:
-
-Custom property | Description | Default
-----------------|-------------|----------
-`--paper-button-ink-color` | Background color of the ripple | `Based on the button's color`
-`--paper-button` | Mixin applied to the button | `{}`
-`--paper-button-disabled` | Mixin applied to the disabled button. Note that you can also use the `paper-button[disabled]` selector | `{}`
-`--paper-button-flat-keyboard-focus` | Mixin applied to a flat button after it's been focused using the keyboard | `{}`
-`--paper-button-raised-keyboard-focus` | Mixin applied to a raised button after it's been focused using the keyboard | `{}`

-/**
-Material design:
-[Buttons](https://www.google.com/design/spec/components/buttons.html)
-
-`paper-button` is a button. When the user touches the button, a ripple effect
-emanates from the point of contact. It may be flat or raised. A raised button is
-styled with a shadow.
-
-Example:
-
-    <paper-button>Flat button</paper-button>
-    <paper-button raised>Raised button</paper-button>
-    <paper-button noink>No ripple effect</paper-button>
-    <paper-button toggles>Toggle-able button</paper-button>
-
-A button that has `toggles` true will remain `active` after being clicked (and
-will have an `active` attribute set). For more information, see the
-`IronButtonState` behavior.
-
-You may use custom DOM in the button body to create a variety of buttons. For
-example, to create a button with an icon and some text:
-
-    <paper-button>
-      <iron-icon icon="favorite"></iron-icon>
-      custom button content
-    </paper-button>
-
-To use `paper-button` as a link, wrap it in an anchor tag. Since `paper-button`
-will already receive focus, you may want to prevent the anchor tag from
-receiving focus as well by setting its tabindex to -1.
-
-    <a href="https://www.polymer-project.org/" tabindex="-1">
-      <paper-button raised>Polymer Project</paper-button>
-    </a>
-
-### Styling
-
-Style the button with CSS as you would a normal DOM element.
-
-    paper-button.fancy {
-      background: green;
-      color: yellow;
-    }
-
-    paper-button.fancy:hover {
-      background: lime;
-    }
-
-    paper-button[disabled],
-    paper-button[toggles][active] {
-      background: red;
-    }
-
-By default, the ripple is the same color as the foreground at 25% opacity. You
-may customize the color using the `--paper-button-ink-color` custom property.
-
-The following custom properties and mixins are also available for styling:
-
-Custom property | Description | Default
-----------------|-------------|----------
-`--paper-button-ink-color` | Background color of the ripple | `Based on the button's color`
-`--paper-button` | Mixin applied to the button | `{}`
-`--paper-button-disabled` | Mixin applied to the disabled button. Note that you can also use the `paper-button[disabled]` selector | `{}`
-`--paper-button-flat-keyboard-focus` | Mixin applied to a flat button after it's been focused using the keyboard | `{}`
-`--paper-button-raised-keyboard-focus` | Mixin applied to a raised button after it's been focused using the keyboard | `{}`

-Material design: [Surface
-reaction](https://www.google.com/design/spec/animation/responsive-interaction.html#responsive-interaction-surface-reaction)
-
-`paper-ripple` provides a visual effect that other paper elements can
-use to simulate a rippling effect emanating from the point of contact.  The
-effect can be visualized as a concentric circle with motion.
-
-Example:
-
-    <div style="position:relative">
-      <paper-ripple></paper-ripple>
-    </div>
-
-Note, it's important that the parent container of the ripple be relative
-position, otherwise the ripple will emanate outside of the desired container.
-
-`paper-ripple` listens to "mousedown" and "mouseup" events so it would display
-ripple effect when touches on it.  You can also defeat the default behavior and
-manually route the down and up actions to the ripple element.  Note that it is
-important if you call `downAction()` you will have to make sure to call
-`upAction()` so that `paper-ripple` would end the animation loop.
-
-Example:
-
-    <paper-ripple id="ripple" style="pointer-events: none;"></paper-ripple>
-    ...
-    downAction: function(e) {
-      this.$.ripple.downAction(e.detail);
-    },
-    upAction: function(e) {
-      this.$.ripple.upAction();
-    }
-
-Styling ripple effect:
-
-  Use CSS color property to style the ripple:
-
-    paper-ripple {
-      color: #4285f4;
-    }
-
-  Note that CSS color property is inherited so it is not required to set it on
-  the `paper-ripple` element directly.
-
-By default, the ripple is centered on the point of contact.  Apply the
-`recenters` attribute to have the ripple grow toward the center of its
-container.
-
-    <paper-ripple recenters></paper-ripple>
-
-You can also  center the ripple inside its container from the start.
-
-    <paper-ripple center></paper-ripple>
-
-Apply `circle` class to make the rippling effect within a circle.
-
-    <paper-ripple class="circle"></paper-ripple>

-/**
- * Element implementing the `ArraySelector` mixin, which records
- * dynamic associations between item paths in a master `items` array and a
- * `selected` array such that path changes to the master array (at the host)
- * element or elsewhere via data-binding) are correctly propagated to items
- * in the selected array and vice-versa.
- *
- * The `items` property accepts an array of user data, and via the
- * `select(item)` and `deselect(item)` API, updates the `selected` property
- * which may be bound to other parts of the application, and any changes to
- * sub-fields of `selected` item(s) will be kept in sync with items in the
- * `items` array.  When `multi` is false, `selected` is a property
- * representing the last selected item.  When `multi` is true, `selected`
- * is an array of multiply selected items.
- *
- * Example:
- *
- * ```js
- * import {PolymerElement} from '@polymer/polymer';
- * import '@polymer/polymer/lib/elements/array-selector.js';
- *
- * class EmployeeList extends PolymerElement {

- * Custom element for defining styles in the main document that can take
- * advantage of [shady DOM](https://github.com/webcomponents/shadycss) shims
- * for style encapsulation, custom properties, and custom mixins.
- *
- * - Document styles defined in a `<custom-style>` are shimmed to ensure they
- *   do not leak into local DOM when running on browsers without native
- *   Shadow DOM.
- * - Custom properties can be defined in a `<custom-style>`. Use the `html` selector
- *   to define custom properties that apply to all custom elements.
- * - Custom mixins can be defined in a `<custom-style>`, if you import the optional
- *   [apply shim](https://github.com/webcomponents/shadycss#about-applyshim)
- *   (`shadycss/apply-shim.html`).
- *
- * To use:
- *
- * - Import `custom-style.html`.
- * - Place a `<custom-style>` element in the main document, wrapping an inline `<style>` tag that
- *   contains the CSS rules you want to shim.
- *
- * For example:
- *
- * ```html
- * <!-- import apply shim--only required if using mixins -->
- * <link rel="import" href="bower_components/shadycss/apply-shim.html">
- * <!-- import custom-style element -->

-/**
- * The `<dom-repeat>` element will automatically stamp and binds one instance
- * of template content to each object in a user-provided array.
- * `dom-repeat` accepts an `items` property, and one instance of the template
- * is stamped for each item into the DOM at the location of the `dom-repeat`
- * element.  The `item` property will be set on each instance's binding
- * scope, thus templates should bind to sub-properties of `item`.
- *
- * Example:
- *
- * ```html
- * <dom-module id="employee-list">
- *
- *   <template>
- *
- *     <div> Employee list: </div>
- *     <dom-repeat items="{{employees}}">
- *       <template>
- *         <div>First name: <span>{{item.first}}</span></div>
- *         <div>Last name: <span>{{item.last}}</span></div>
- *       </template>
- *     </dom-repeat>
- *
- *   </template>
- *
- * </dom-module>
- * ```
- *
- * With the following custom element definition:
- *
- * ```js
- * class EmployeeList extends PolymerElement {
- *   static get is() { return 'employee-list'; }
- *   static get properties() {
- *     return {
- *       employees: {
- *         value() {
- *           return [
- *             {first: 'Bob', last: 'Smith'},
- *             {first: 'Sally', last: 'Johnson'},
- *             ...
- *           ];
- *         }
- *       }
- *     };
- *   }
- * }
- * ```
- *
- * Notifications for changes to items sub-properties will be forwarded to template
- * instances, which will update via the normal structured data notification system.
- *
- * Mutations to the `items` array itself should be made using the Array
- * mutation API's on the PropertyEffects mixin (`push`, `pop`, `splice`,
- * `shift`, `unshift`), and template instances will be kept in sync with the
- * data in the array.
- *
- * Events caught by event handlers within the `dom-repeat` template will be
- * decorated with a `model` property, which represents the binding scope for
- * each template instance.  The model should be used to manipulate data on the
- * instance, for example `event.model.set('item.checked', true);`.
- *
- * Alternatively, the model for a template instance for an element stamped by
- * a `dom-repeat` can be obtained using the `modelForElement` API on the
- * `dom-repeat` that stamped it, for example
- * `this.$.domRepeat.modelForElement(event.target).set('item.checked', true);`.
- * This may be useful for manipulating instance data of event targets obtained
- * by event handlers on parents of the `dom-repeat` (event delegation).
- *
- * A view-specific filter/sort may be applied to each `dom-repeat` by supplying a
- * `filter` and/or `sort` property.  This may be a string that names a function on
- * the host, or a function may be assigned to the property directly.  The functions
- * should implemented following the standard `Array` filter/sort API.
- *
- * In order to re-run the filter or sort functions based on changes to sub-fields
- * of `items`, the `observe` property may be set as a space-separated list of
- * `item` sub-fields that should cause a re-filter/sort when modified.  If
- * the filter or sort function depends on properties not contained in `items`,
- * the user should observe changes to those properties and call `render` to update
- * the view based on the dependency change.
- *
- * For example, for an `dom-repeat` with a filter of the following:
- *
- * ```js
- * isEngineer(item) {
- *   return item.type == 'engineer' || item.manager.type == 'engineer';
- * }
- * ```
- *
- * Then the `observe` property should be configured as follows:
- *
- * ```html
- * <dom-repeat items="{{employees}}" filter="isEngineer" observe="type manager.type">
- * ```
- *

- * @polymer

-// (3) B.created, (4) element.created. There was no support for

-// 2.x
-// Behaviors are made into proper mixins which live in the

-/* Note about construction and extension of legacy classes.
-  [Changed in Q4 2018 to optimize performance.]
-
-  When calling `Polymer` or `mixinBehaviors`, the generated class below is
-  made. The list of behaviors was previously made into one generated class per
-  behavior, but this is no longer the case as behaviors are now called
-  manually. Note, there may *still* be multiple generated classes in the
-  element's prototype chain if extension is used with `mixinBehaviors`.
-
-  The generated class is directly tied to the info object and behaviors
-  used to create it. That list of behaviors is filtered so it's only the
-  behaviors not active on the superclass. In order to call through to the
-  entire list of lifecycle methods, it's important to call `super`.
-
-  The element's `properties` and `observers` are controlled via the finalization
-  mechanism provided by `PropertiesMixin`. `Properties` and `observers` are
-  collected by manually traversing the prototype chain and merging.

-/**
- * Generates a class that extends `LegacyElement` based on the
- * provided info object.  Metadata objects on the `info` object
- * (`properties`, `observers`, `listeners`, `behaviors`, `is`) are used
- * for Polymer's meta-programming systems, and any functions are copied
- * to the generated class.
- *
- * Valid "metadata" values are as follows:
- *
- * `is`: String providing the tag name to register the element under. In
- * addition, if a `dom-module` with the same id exists, the first template
- * in that `dom-module` will be stamped into the shadow root of this element,
- * with support for declarative event listeners (`on-...`), Polymer data
- * bindings (`[[...]]` and `{{...}}`), and id-based node finding into
- * `this.$`.
- *
- * `properties`: Object describing property-related metadata used by Polymer
- * features (key: property names, value: object containing property metadata).
- * Valid keys in per-property metadata include:
- * - `type` (String|Number|Object|Array|...): Used by
- *   `attributeChangedCallback` to determine how string-based attributes
- *   are deserialized to JavaScript property values.
- * - `notify` (boolean): Causes a change in the property to fire a
- *   non-bubbling event called `<property>-changed`. Elements that have
- *   enabled two-way binding to the property use this event to observe changes.
- * - `readOnly` (boolean): Creates a getter for the property, but no setter.
- *   To set a read-only property, use the private setter method
- *   `_setProperty(property, value)`.
- * - `observer` (string): Observer method name that will be called when
- *   the property changes. The arguments of the method are
- *   `(value, previousValue)`.
- * - `computed` (string): String describing method and dependent properties
- *   for computing the value of this property (e.g. `'computeFoo(bar, zot)'`).
- *   Computed properties are read-only by default and can only be changed
- *   via the return value of the computing method.
- *
- * `observers`: Array of strings describing multi-property observer methods
- *  and their dependent properties (e.g. `'observeABC(a, b, c)'`).
- *
- * `listeners`: Object describing event listeners to be added to each
- *  instance of this element (key: event name, value: method name).
- *
- * `behaviors`: Array of additional `info` objects containing metadata
- * and callbacks in the same format as the `info` object here which are
- * merged into this element.
- *
- * `hostAttributes`: Object listing attributes to be applied to the host
- *  once created (key: attribute name, value: attribute value).  Values
- *  are serialized based on the type of the value.  Host attributes should
- *  generally be limited to attributes such as `tabIndex` and `aria-...`.
- *  Attributes in `hostAttributes` are only applied if a user-supplied
- *  attribute is not already present (attributes in markup override
- *  `hostAttributes`).
- *
- * In addition, the following Polymer-specific callbacks may be provided:
- * - `registered`: called after first instance of this element,
- * - `created`: called during `constructor`
- * - `attached`: called during `connectedCallback`
- * - `detached`: called during `disconnectedCallback`
- * - `ready`: called before first `attached`, after all properties of
- *   this element have been propagated to its template and all observers
- *   have run
- *
- * @param {!PolymerInit} info Object containing Polymer metadata and functions
- *   to become class methods.
- * @template T
- * @param {function(T):T} mixin Optional mixin to apply to legacy base class
- *   before extending with Polymer metaprogramming.
- * @return {function(new:HTMLElement)} Generated class

- * The `Templatizer` behavior adds methods to generate instances of
- * templates that are each managed by an anonymous `PropertyEffects`
- * instance where data-bindings in the stamped template content are bound to
- * accessors on itself.
- *
- * This behavior is provided in Polymer 2.x-3.x as a hybrid-element convenience
- * only.  For non-hybrid usage, the `Templatize` library
- * should be used instead.
- *
- * Example:
- *
- *     import {dom} from '@polymer/polymer/lib/legacy/polymer.dom.js';
- *     // Get a template from somewhere, e.g. light DOM
- *     let template = this.querySelector('template');
- *     // Prepare the template
- *     this.templatize(template);
- *     // Instance the template with an initial data model
- *     let instance = this.stamp({myProp: 'initial'});
- *     // Insert the instance's DOM somewhere, e.g. light DOM
- *     dom(this).appendChild(instance.root);
- *     // Changing a property on the instance will propagate to bindings
- *     // in the template
- *     instance.myProp = 'new value';
- *
- * Users of `Templatizer` may need to implement the following abstract
- * API's to determine how properties and paths from the host should be
- * forwarded into to instances:
- *
- *     _forwardHostPropV2: function(prop, value)
- *
- * Likewise, users may implement these additional abstract API's to determine
- * how instance-specific properties that change on the instance should be
- * forwarded out to the host, if necessary.
- *
- *     _notifyInstancePropV2: function(inst, prop, value)
- *
- * In order to determine which properties are instance-specific and require
- * custom notification via `_notifyInstanceProp`, define an `_instanceProps`
- * object containing keys for each instance prop, for example:
- *
- *     _instanceProps: {
- *       item: true,
- *       index: true
- *     }
- *
- * Any properties used in the template that are not defined in _instanceProp
- * will be forwarded out to the Templatize `owner` automatically.
- *
- * Users may also implement the following abstract function to show or
- * hide any DOM generated using `stamp`:
- *
- *     _showHideChildren: function(shouldHide)
- *
- * Note that some callbacks are suffixed with `V2` in the Polymer 2.x behavior
- * as the implementations will need to differ from the callbacks required
- * by the 1.x Templatizer API due to changes in the `TemplateInstance` API
- * between versions 1.x and 2.x.

-/**
- * Element class mixin that provides the core API for Polymer's meta-programming
- * features including template stamping, data-binding, attribute deserialization,
- * and property change observation.
- *
- * Subclassers may provide the following static getters to return metadata
- * used to configure Polymer's features for the class:
- *
- * - `static get is()`: When the template is provided via a `dom-module`,
- *   users should return the `dom-module` id from a static `is` getter.  If
- *   no template is needed or the template is provided directly via the
- *   `template` getter, there is no need to define `is` for the element.
- *
- * - `static get template()`: Users may provide the template directly (as
- *   opposed to via `dom-module`) by implementing a static `template` getter.
- *   The getter must return an `HTMLTemplateElement`.
- *
- * - `static get properties()`: Should return an object describing
- *   property-related metadata used by Polymer features (key: property name
- *   value: object containing property metadata). Valid keys in per-property
- *   metadata include:
- *   - `type` (String|Number|Object|Array|...): Used by
- *     `attributeChangedCallback` to determine how string-based attributes
- *     are deserialized to JavaScript property values.
- *   - `notify` (boolean): Causes a change in the property to fire a
- *     non-bubbling event called `<property>-changed`. Elements that have
- *     enabled two-way binding to the property use this event to observe changes.
- *   - `readOnly` (boolean): Creates a getter for the property, but no setter.
- *     To set a read-only property, use the private setter method
- *     `_setProperty(property, value)`.
- *   - `observer` (string): Observer method name that will be called when
- *     the property changes. The arguments of the method are
- *     `(value, previousValue)`.
- *   - `computed` (string): String describing method and dependent properties
- *     for computing the value of this property (e.g. `'computeFoo(bar, zot)'`).
- *     Computed properties are read-only by default and can only be changed
- *     via the return value of the computing method.
- *
- * - `static get observers()`: Array of strings describing multi-property
- *   observer methods and their dependent properties (e.g.
- *   `'observeABC(a, b, c)'`).
- *
- * The base class provides default implementations for the following standard
- * custom element lifecycle callbacks; users may override these, but should
- * call the super method to ensure
- * - `constructor`: Run when the element is created or upgraded
- * - `connectedCallback`: Run each time the element is connected to the
- *   document
- * - `disconnectedCallback`: Run each time the element is disconnected from
- *   the document
- * - `attributeChangedCallback`: Run each time an attribute in
- *   `observedAttributes` is set or removed (note: this element's default
- *   `observedAttributes` implementation will automatically return an array
- *   of dash-cased attributes based on `properties`)

- * @polymer
- * @appliesMixin PropertyEffects
- * @appliesMixin PropertiesMixin
- * @property rootPath {string} Set to the value of `rootPath`,
- *   which defaults to the main document path
- * @property importPath {string} Set to the value of the class's static
- *   `importPath` property, which defaults to the path of this element's
- *   `dom-module` (when `is` is used), but can be overridden for other
- *   import strategies.

-   * The info object should contain property metadata as follows:
-   *
-   * * `type`: {function} type to which an attribute matching the property
-   * is deserialized. Note the property is camel-cased from a dash-cased
-   * attribute. For example, 'foo-bar' attribute is deserialized to a
-   * property named 'fooBar'.
-   *
-   * * `readOnly`: {boolean} creates a readOnly property and
-   * makes a private setter for the private of the form '_setFoo' for a
-   * property 'foo',
-   *
-   * * `computed`: {string} creates a computed property. A computed property
-   * is also automatically set to `readOnly: true`. The value is calculated
-   * by running a method and arguments parsed from the given string. For
-   * example 'compute(foo)' will compute a given property when the
-   * 'foo' property changes by executing the 'compute' method. This method
-   * must return the computed value.
-   *
-   * * `reflectToAttribute`: {boolean} If true, the property value is reflected
-   * to an attribute of the same name. Note, the attribute is dash-cased
-   * so a property named 'fooBar' is reflected as 'foo-bar'.
-   *
-   * * `notify`: {boolean} sends a non-bubbling notification event when
-   * the property changes. For example, a property named 'foo' sends an
-   * event named 'foo-changed' with `event.detail` set to the value of
-   * the property.
-   *
-   * * observer: {string} name of a method that runs when the property
-   * changes. The arguments of the method are (value, previousValue).
-   *
-   * Note: Users may want control over modifying property
-   * effects via subclassing. For example, a user might want to make a
-   * reflectToAttribute property not do so in a subclass. We've chosen to
-   * disable this because it leads to additional complication.
-   * For example, a readOnly effect generates a special setter. If a subclass
-   * disables the effect, the setter would fail unexpectedly.
-   * Based on feedback, we may want to try to make effects more malleable

- * -   Call `this._enableProperties()` in the element's `connectedCallback` to

-     *
-     * - `dependencies` - Array containing trigger metadata for each property
-     *   that should trigger the binding to update
-     * - `literal` - String containing text if the part represents a literal;
-     *   in this case no `dependencies` are needed
-     *
-     * Additional metadata for use by `_evaluateBinding` may be provided in
-     * each part object as needed.
-     *
-     * The default implementation handles the following types of bindings
-     * (one or more may be intermixed with literal strings):
-     * - Property binding: `[[prop]]`
-     * - Path binding: `[[object.prop]]`
-     * - Negated property or path bindings: `[[!prop]]` or `[[!object.prop]]`
-     * - Two-way property or path bindings (supports negation):
-     *   `{{prop}}`, `{{object.prop}}`, `{{!prop}}` or `{{!object.prop}}`
-     * - Inline computed method (supports negation):
-     *   `[[compute(a, 'literal', b)]]`, `[[!compute(a, 'literal', b)]]`
-     *
-     * The default implementation uses a regular expression for best
-     * performance. However, the regular expression uses a white-list of
-     * allowed characters in a data-binding, which causes problems for
-     * data-bindings that do use characters not in this white-list.
-     *
-     * Instead of updating the white-list with all allowed characters,
-     * there is a StrictBindingParser (see lib/mixins/strict-binding-parser)
-     * that uses a state machine instead. This state machine is able to handle
-     * all characters. However, it is slightly less performant, therefore we
-     * extracted it into a separate optional mixin.

- * Helper api for enqueuing client dom created by a host element.
- *
- * By default elements are flushed via `_flushProperties` when

- * This provides an ordering guarantee that the client dom an element
- * creates is flushed before the element itself (i.e. client `ready`
- * fires before host `ready`).
- *
- * However, if `_flushProperties` is called *before* an element is connected,
- * as for example `Templatize` does, this ordering guarantee cannot be
- * satisfied because no elements are connected. (Note: Bound elements that
- * receive data do become enqueued clients and are properly ordered but
- * unbound elements are not.)
- *
- * To maintain the desired "client before host" ordering guarantee for this
- * case we rely on the "host stack. Client nodes registers themselves with
- * the creating host element when created. This ensures that all client dom
- * is readied in the proper order, maintaining the desired guarantee.

- * A template literal tag that creates an HTML <template> element from the

- * attacks; however, `htmlLiteral` can be used to compose static
- * string values into templates. This is useful to compose strings into
- * places that do not accept html, like the css text of a `style`
- * element.

-/**
- * Module for preparing and stamping instances of templates that utilize
- * Polymer's data-binding and declarative event listener features.
- *
- * Example:
- *
- *     // Get a template from somewhere, e.g. light DOM
- *     let template = this.querySelector('template');
- *     // Prepare the template
- *     let TemplateClass = Templatize.templatize(template);
- *     // Instance the template with an initial data model
- *     let instance = new TemplateClass({myProp: 'initial'});
- *     // Insert the instance's DOM somewhere, e.g. element's shadow DOM
- *     this.shadowRoot.appendChild(instance.root);
- *     // Changing a property on the instance will propagate to bindings
- *     // in the template
- *     instance.myProp = 'new value';
- *
- * The `options` dictionary passed to `templatize` allows for customizing
- * features of the generated template class, including how outer-scope host
- * properties should be forwarded into template instances, how any instance
- * properties added into the template's scope should be notified out to
- * the host, and whether the instance should be decorated as a "parent model"
- * of any event handlers.
- *
- *     // Customize property forwarding and event model decoration
- *     let TemplateClass = Templatize.templatize(template, this, {
- *       parentModel: true,
- *       forwardHostProp(property, value) {...},
- *       instanceProps: {...},
- *       notifyInstanceProp(instance, property, value) {...},
- *     });
- *
- * @summary Module for preparing and stamping instances of templates
- *   utilizing Polymer templating features.

-/**
- * Returns an anonymous `PropertyEffects` class bound to the
- * `<template>` provided.  Instancing the class will result in the
- * template being stamped into a document fragment stored as the instance's
- * `root` property, after which it can be appended to the DOM.
- *
- * Templates may utilize all Polymer data-binding features as well as
- * declarative event listeners.  Event listeners and inline computing
- * functions in the template will be called on the host of the template.
- *
- * The constructor returned takes a single argument dictionary of initial
- * property values to propagate into template bindings.  Additionally
- * host properties can be forwarded in, and instance properties can be
- * notified out by providing optional callbacks in the `options` dictionary.
- *
- * Valid configuration in `options` are as follows:
- *
- * - `forwardHostProp(property, value)`: Called when a property referenced
- *   in the template changed on the template's host. As this library does
- *   not retain references to templates instanced by the user, it is the
- *   templatize owner's responsibility to forward host property changes into
- *   user-stamped instances.  The `instance.forwardHostProp(property, value)`
- *    method on the generated class should be called to forward host
- *   properties into the template to prevent unnecessary property-changed
- *   notifications. Any properties referenced in the template that are not
- *   defined in `instanceProps` will be notified up to the template's host
- *   automatically.
- * - `instanceProps`: Dictionary of property names that will be added
- *   to the instance by the templatize owner.  These properties shadow any
- *   host properties, and changes within the template to these properties
- *   will result in `notifyInstanceProp` being called.
- * - `mutableData`: When `true`, the generated class will skip strict
- *   dirty-checking for objects and arrays (always consider them to be
- *   "dirty").
- * - `notifyInstanceProp(instance, property, value)`: Called when
- *   an instance property changes.  Users may choose to call `notifyPath`
- *   on e.g. the owner to notify the change.
- * - `parentModel`: When `true`, events handled by declarative event listeners
- *   (`on-event="handler"`) will be decorated with a `model` property pointing
- *   to the template instance that stamped it.  It will also be returned
- *   from `instance.parentModel` in cases where template instance nesting
- *   causes an inner model to shadow an outer model.
- *
- * All callbacks are called bound to the `owner`. Any context
- * needed for the callbacks (such as references to `instances` stamped)
- * should be stored on the `owner` such that they can be retrieved via
- * `this`.
- *
- * When `options.forwardHostProp` is declared as an option, any properties
- * referenced in the template will be automatically forwarded from the host of
- * the `<template>` to instances, with the exception of any properties listed in
- * the `options.instanceProps` object.  `instanceProps` are assumed to be
- * managed by the owner of the instances, either passed into the constructor
- * or set after the fact.  Note, any properties passed into the constructor will
- * always be set to the instance (regardless of whether they would normally
- * be forwarded from the host).
- *
- * Note that `templatize()` can be run only once for a given `<template>`.
- * Further calls will result in an error. Also, there is a special
- * behavior if the template was duplicated through a mechanism such as
- * `<dom-repeat>` or `<test-fixture>`. In this case, all calls to
- * `templatize()` return the same class for all duplicates of a template.
- * The class returned from `templatize()` is generated only once using
- * the `options` from the first call. This means that any `options`
- * provided to subsequent calls will be ignored. Therefore, it is very
- * important not to close over any variables inside the callbacks. Also,
- * arrow functions must be avoided because they bind the outer `this`.
- * Inside the callbacks, any contextual information can be accessed
- * through `this`, which points to the `owner`.
- *
- * @param {!HTMLTemplateElement} template Template to templatize
- * @param {Polymer_PropertyEffects=} owner Owner of the template instances;
- *   any optional callbacks will be bound to this owner.
- * @param {Object=} options Options dictionary (see summary for details)
- * @return {function(new:TemplateInstanceBase)} Generated class bound to the template
- *   provided

-/*
- * The apply shim simulates the behavior of `@apply` proposed at
- * https://tabatkins.github.io/specs/css-apply-rule/.
- * The approach is to convert a property like this:
- *
- *    --foo: {color: red; background: blue;}
- *
- * to this:
- *
- *    --foo_-_color: red;
- *    --foo_-_background: blue;
- *
- * Then where `@apply --foo` is used, that is converted to:
- *
- *    color: var(--foo_-_color);
- *    background: var(--foo_-_background);
- *
- * This approach generally works but there are some issues and limitations.
- * Consider, for example, that somewhere *between* where `--foo` is set and used,
- * another element sets it to:
- *
- *    --foo: { border: 2px solid red; }
- *
- * We must now ensure that the color and background from the previous setting
- * do not apply. This is accomplished by changing the property set to this:
- *
- *    --foo_-_border: 2px solid red;
- *    --foo_-_color: initial;
- *    --foo_-_background: initial;
- *
- * This works but introduces one new issue.
- * Consider this setup at the point where the `@apply` is used:
- *
- *    background: orange;
- *    `@apply` --foo;
- *
- * In this case the background will be unset (initial) rather than the desired
- * `orange`. We address this by altering the property set to use a fallback
- * value like this:
- *
- *    color: var(--foo_-_color);
- *    background: var(--foo_-_background, orange);
- *    border: var(--foo_-_border);
- *
- * Note that the default is retained in the property set and the `background` is
- * the desired `orange`. This leads us to a limitation.
- *
- * Limitation 1:
-
- * Only properties in the rule where the `@apply`
- * is used are considered as default values.
- * If another rule matches the element and sets `background` with
- * less specificity than the rule in which `@apply` appears,
- * the `background` will not be set.
- *
- * Limitation 2:
- *
- * When using Polymer's `updateStyles` api, new properties may not be set for
- * `@apply` properties.
