Added a new option reduceOnly to get the reduced basis from a Grobner basis.
Example:
  (cohom.sm1) run
  [ [[1 1 1 1] [0 1 3 4]] [1 2]] gkz gb 0 get /ff set
  [ff [(reduceOnly)]] groebner_sugar 0 get /gg set
  gg is the reduced Grobner basis.

An implementation of the partial tangent cone algorithm, i.e., reduction
in Q(x')_0 [x''] <D,h>  (x' : localized, x'' : global).

Example:
/ecart.checkOrder { 1 } def
[(DebugReductionEcart) 3] system_variable
[ [(1-x-y-z) (1-z)] (x,y,z)
  [ [(y) -1 (z) -1 (Dy) 1 (Dz) 1] [(x) 1 (Dx) 1]]
  [(partialEcartGlobalVarX) [(x)]] ] ecart.gb /ff set

It is a computation in Q(y,z)_0 [x] <Dx,Dy,Dz,h>.
