Selectables, Tables, FROM objects
=================================
The term "selectable" refers to any object that rows can be selected from;
in SQLAlchemy, these objects descend from :class:`.FromClause` and their
distinguishing feature is their :attr:`.FromClause.c` attribute, which is
a namespace of all the columns contained within the FROM clause (these
elements are themselves :class:`.ColumnElement` subclasses).
