-  Synopsis    [This procedure is similar to Cudd_ShuffleHeap() and Cudd_bddPermute().]
-
-  Description [The first argument is the REO manager. The 2nd/3d
-  arguments are the function and its CUDD manager. The last argument
-  is the permutation to be implemented. The i-th entry of the permutation 
-  array contains the index of the variable that should be brought to the 
-  i-th level.  The size of the array should be equal or greater to 
-  the number of variables currently in use (that is, the size of CUDD
-  manager and the size of REO manager).]
-
-  SideEffects [Note that the resulting BDD is not referenced.]
