\class CategoryMenu
\brief The CategoryMenu widget aids in filtering records or files by Category.
The CategoryMenu widget provides a popup menu that will make filtering records
or files by category much easier. The widget will lookup the available
categories for an application, populate the menu, and keep a track of which
categories are being filtered against. A set of categories can be tested
by the isSelected() function to see if a record or file containing those
categories would be allowed through by the filter.
\warning Currently this class is not suitable for extending.

menu, hence changing what records or files should be selected.
