    Implements a frame that enables one or more user-defined routines in the
    snippets database to be selected. It displays a two-level tree of snippets
    categories with their associated user-defined routines. Each category and
    routine has a check box that can be checked to select them. A property is
    exposed that gives access to selected routines.
