==========================================================================================================================================

A module that allows multiple handlers to respond to single wxWidgets
events.  This allows true NxN Observer/Observable connections: One
event can be received by multiple handlers, and one handler can
receive multiple events.

There are two ways to register event handlers.  The first way is
similar to standard wxPython handler registration::

    from wx.lib.evtmgr import eventManager
    eventManager.Register(handleEvents, EVT_BUTTON, win=frame, id=101)

There's also a new object-oriented way to register for events.  This
invocation is equivalent to the one above, but does not require the
programmer to declare or track control ids or parent containers::

    eventManager.Register(handleEvents, EVT_BUTTON, myButton)
