  Header File:  ICC Profile.H

  This defines the C++ class we encapsulate the profile in.  It also defines
  the base class for device enumeration.  All activity related to the profile,
  including installations, associations, and so forth, is encapsulated in the
  CProfile class.  The UI classes themselves never call an ICM API, but are
  instead concerned with simply handling the interface.

  Change History:

  10-31-96  A-RobKj (Pretty Penny Enterprises) began encapsulating
  11-22-96  A-RobKj changed associations from string array to uint array to
                    facilitate the spec'd device naming conventions, and
                    filtering of lists for previously installed devices.

  12-04-96  A-RobKj Added the CProfileArray class to make the Device
                    management UI more efficient.

  12-13-96  A-RobKj Moved the CDeviceList derived classes here, so I can use
                    them elsewhere.

  Highlights:

  This is a base class for the enumeration and reporting of Device
  class-specific information.  The spec is such that a device can be associated
  with a friendly name, but displayed in the UI with an enhanced name.  Also,
  the method for enumerating a device can differ from class to class.

  This base class is usable for cases where there is no means of enumerating
  devices currently.  It reports that there are no devices.
  To make overrides easier, the default display name returns the friendly name,
  so derived classes where this is the case do not need to override this
  method.
