 [(groebner_sugar computes Groebner basis by the sugar strategy.)
  (Format of arguments and results are as same as that of groebner.)
  (See groebner.  When you compute in the ring of polynomials,)
  $it is recommended to turn on the switch [(UseCriterion1) 1] system_variable$
  (Note that groebner_sugar does not use the homogenized Weyl algebra.)
  (So, it does work only for term orders. Never use negative weight vectors.)
