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>.
