Description (last modified by )
The parent Polyhedra(QQ, 3) is the set of polyhedra whose vertices/rays/lines are in QQ^3 and whose facets/equalities are in QQ^{3+1}.
We define parents corresponding to more general, finite or infinite, allowed sets of vertices/rays/lines, facets/equalities.
The category PolyhedralSets currently makes every parent an additive monoid (Minkowski sums). This will need to be changed -- the parent will be an additive monoid only if the sets of vertices/rays/lines, facets/equalities are.
