    HISTORY:
    07/16/02  awi		Pulled out of PsychPlatform.h
    
    DESCRIPTION:
    
    PsychPlatformConstants defines constants which identify all OSes and binding 
    languages
    
    PsychPlatformContstants is at the base of the PsychToolbox header file inclusion
    hierarchy.  Psychtoolbox projects and libraries should include PsychConstants.h 
    or Psych.h, and not include PsychPlatformConstants directly.  
    
    The inclusion order is this:
    
    1> PsychPlatformConstants.h  
      Defines constants which identiy all OSes and binding languages.
    2> PsychPlatform.h
      Defines constants which assert the platform, language, and debugging. 
    3> PsychIncludes.h 
      Includes all standard C, language, and system headers.
    4> PsychConstants
      Abstracts types.
    5a> MiniBox.h
    5b> ...
    6> Psych.h
      Includes everything a PsychToolbox project should need.
