  27     Makes a class publically usable. This function must not be called
  28     before MakeClass().
  29
  30     INPUTS
  31     class - The result of MakeClass()
  32
  33     RESULT
  34     None.

  36     NOTES
  37     Do not use this function for private classes.

  41     BUGS
  42     There is no protection against creating multiple classes with
  43     the same name yet. The operation of the system is undefined
  44     in this case.
