getHWnd - retrieve the underlying Windows handle for Matlab figure(s)

Syntax:
hWnd = gethwnd(hFig)

Description:
HWnd = GETHWND retrieves the current figure (gcf)'s underlying Windows handle, thus enabling integration of Matlab GUI in C/C++/C# programs.
HWnd = GETHWND(hFig) retrieves a specific figure's underlying Windows handle. hFig is a Matlab handle, or a list of handles (not necessarily figure handle(s) - the handles' containing figure is used).

Limitations:
Windows-only (duh!); Java must be enabled

Warning:
This code heavily relies on undocumented and unsupported Matlab functionality. It works on Matlab 7+, but use at your own risk!
