; Description:      Splitter Bar demo
;
; Requirement:      Beta
; Author(s):        eltorro (Steve Podhajecki <gehossafats@netmdc.com>)
; Note(s):			This is just a proof of concept at the moment.
;					This could be tweaked into a udf with a little more work
;					The basic principle is to create a pic box and drag it
;					then resize the controls.
;					I bowwored some filler for the tree and list from the help files.
