*peer class
*
*features:
*58839 Add a method to query closing a Frame, this required a change that included added a new event (FrameEvent and the corresponding
*FrameEventHandler) and a method, bool Frame::allowClose()
*
*Also made fixes in the VCF Builder to now take advantage of this, so the MainWindow class will now register an event
*handler to handler the FrameClosing event, and attempt to set the current workspace to NULL. If this does not happen then
*the closing event will fail and prevent the widnow from being shutdown. Woo hoo !
