+// Parses INI files in a string. Users should in inherit from this class.
+// This is a very basic INI parser with these characteristics:
+//  - Ignores blank lines.
+//  - Ignores comment lines beginning with '#' or ';'.
+//  - Duplicate key names in the same section will simply cause repeated calls
+//    to HandleTriplet with the same |section| and |key| parameters.
+//  - No escape characters supported.
+//  - Global properties result in calls to HandleTriplet with an empty string in
+//    the |section| argument.
+//  - Section headers begin with a '[' character. It is recommended, but
+//    not required to close the header bracket with a ']' character. All
+//    characters after a closing ']' character is ignored.
+//  - Key value pairs are indicated with an '=' character. Whitespace is not
+//    ignored. Quoting is not supported. Everything before the first '='
+//    is considered the |key|, and everything after is the |value|.
