// CButton-derived class to make using groups easier. CGroupControl will 
// automatically show/hide or enable/disable controls within the group when 
// the group is shown/hidden or enabled/disabled. Also, if the group box is 
// moved then its controls are moved with it.
//

// you continue to acknowledge me as the original author in this source code,
// or any code derived from it.

// If you use this code, or use it as a base for your own code, it would be 
// nice to hear from you simply so I know it's not been a waste of time!
