  Source File:  ICC Profile.CPP

  This implements the class we use to encapsulate everything we will ever care
  to know about a profile, including the classes we need to support
  associations and the like.

  A Pretty Penny Enterprises Production

  Change History:

  10-31-96  A-RobKj (Pretty Penny Enterprises) began encapsulating it
  12-04-96  A-RobKj Added the CProfileArray and CAllDeviceList classes
  12-13-96  A-RobKj Modified for faster operation (more lazy evaluation,
                    and common DLL-wide database for installation checks)
                    Also moved CDeviceList derived classes to the header, so
                    I can use them other places, as well...
  01-07-97  [email protected]  Fixed CProfileArray::Empty- wasn't setting Next
            object pointer to NULL after deleting said object (Fixed GP fault).
  01-08-97  [email protected]  Modified printer enumeration routine to only
            enumerate color models (uses Global utility function).
