[1995, 8/17,A] :  (t^0).  returns 0.

[1995, 8/17,B] :  Hbook/Mprog/apery.m
              reduction in module.  
   ---> fixed: isSameComponent(), grade_module1() (redm.c)
               homogenizeObject (kanExport1.c)
        Question: The degree of "e" was ignored before. For example,
                  e x + x    was homogeneous. But, in the new grade(),
                  e x + x h   is homogeneous.  Does the other program
                  works correctly?
        A. Doc/cv0.sm1 ---> OK.
           resolution macros does NOT works, because of the change of
           homogenize.----> OK.
