/**
* The context module provides functions to get at the context element
* for widgets.
*
* Many widgets are created dynamically and append themselves to the
* body so that they can be shown to the user. The context element is
* just a div appended to the body, that provides a common parent for
* these widget elements.
*
* Appending widget elements to the context element provides two benefits:
* 1 - it would be cleaner for all aloha-specific elements to be
* appended to one common parent.
* 2 - all css rules should have a .aloha context class, and the common
* parent provides this class.
