 Moving the parameters around to clean up the directories.
 r18392@shi:  ted | 2008-03-08 21:57:14 -0800
 Moving the 'get' function to cpp
 r18870@shi:  ted | 2008-04-03 21:10:20 -0700
 Adding in to the parameter prototype the ability to have a gui-tip and a gui-hidden parameter
 r18871@shi:  ted | 2008-04-03 21:17:39 -0700
 Using the _gui-hidden parameter to block the creation of the widget if set.
