The IDLanROIGroup::Cleanup procedure method performs all cleanup for a region of interest group object.
Cleanup methods are special life cycle methods, and as such cannot be called outside the context of object creation and destruction. This means that in most cases, you cannot call the Cleanup method directly. There is one exception to this rule: If you write your own subclass of this class, you can call the Cleanup method from within the Init or Cleanup method of the subclass.
