//  Control Debug Switch implementation
//=-------------------------------------------------------------------------------
//---------------------------------------------------------------------------
// The following macros allow you declare global BOOL variables that are only
// included in the debug build (they map to FALSE in the retail build).  
// These boolean switches are automatically persisted (in %WINDIR%\ctlswtch.ini) 
// and a console app (ctlswtch.exe) is used to turn on/off the switches.
// All switches must be initialized.  This can be done in the InitializeLibrary()
// routine of each control.  All switches are initialized to FALSE using the
// INIT_SWITCH macro, and to TRUE using the INIT_SWITCH_TRUE macro.
//
//                     
// To declare a switch (global scope), define and intialize the switch e.g.
//
//
//  DEFINE_SWITCH(fContainer);
//
// AND,
//
//  INIT_SWITCH(fContainer);
//
//
// To test whether a switch is currently set (TRUE), use FSWITCH, e.g.
//
//  if (FSWITCH(fContainer))
//    *ppv = (IOleContainer*)this;
//
//
// To reference a switch declared in another file, use EXTERN_SWITCH, e.g.
//
//  EXTERN_SWITCH(fContainer);
//
// AND
//
//  INIT_SWITCH(fContainer);
