Introduction - If you have any usage issues, please Google them yourself
The WAVELETCHANGE dialog is initiated by calling WAVELETCHANGEINIT which
then calls WAVELETCHANGE. With one exception, WAVELETCHANGE is never called
directly from another program. Tha exception is when another program has
a figure handle that may be a legitimate WAVELETCHANGE window or not.
Calling waveletchange( test ,figurehandle) will return 1 if it is a legit
change window and zero otherwise.
