//	Author:     Harrison Ainsworth
//	Date:		05/99
//	Purpose:	be a dialog for inputing a bias/gain choice. to be owned and called from a 
//				CBiasGainGadget
//	Implemen-	DoWithParam() is supplied with a pointer to the owning gadget (in the OpParam), this 
//	tation:		is mainly used to tell the gadget when the dlg is running, which the gadget uses to 
//				ensure that only one (of its) dlgs is running at a time. So: you can have multiple of
//				these biasgain dialogs running, but each is used for a different purpose and is owned 
//				by a separate gadget.
