Add the class MultiAffineFunction which represents functions whose domain is an IntegerPolyhedron and which produce an output given by a tuple of affine expressions in the IntegerPolyhedron's ids. Also add support for piece-wise MultiAffineFunctions, which are defined on a union of IntegerPolyhedrons, and may have different output affine expressions on each IntegerPolyhedron. Thus the function is affine on each individual IntegerPolyhedron piece in the domain. This is part of a series of patches leading up to parametric integer programming. Depends on D118778.
