  1. SUMalg - computes indefinite sums of expressions containing unknown functions and their shifts
  2.  
  3. Calling Sequences
  4.  SUMalg(E,n)
  5.  
  6. Parameters
  7.  E - an expression containing unknown and known functions of the variable n.
  8.  n - the variable with respect to which the summation is performed.
  9.  
  10.  
  11. Remarks
  12. -The non-locality (difference between the highest and lowest shift) of the summand is minimized.
  13. -The form of the summand can effect the summation procedure for rational expressions containing non-monomial terms in the      denominator.  In such cases the result is always corect, though it may not be optimal.
