//This Win32 control is made to be flexible and usable with
//every kind of CPU architechture that has fixed width instruction words.
//Just supply it an instance of a class derived from Debugger, with all methods
//overridden for full functionality. Look at the ppc one for an example.
//
//To add to a dialog box, just draw a User Control in the dialog editor,
//and set classname to "CtrlRegisterList". you also need to call CtrlRegisterList::init()
//before opening this dialog, to register the window class.
//
//To get a class instance to be able to access it, just use 
//  CtrlRegisterList::getFrom(GetDlgItem(yourdialog, IDC_yourid)).
