test if a polyhedral set is contained in the interior of another
Returns true if the polyhedral set ps1 is contained in the interior of the highest dimensional face of ps2, that is if ps1 is a subset of ps2 and the intersections between the facets of ps1 and the facets of ps2 are empty.
A small cube resides in the interior of a larger cube.
The empty set is not in the interior of any other set.
The PolyhedralSets[IsInInterior] command was introduced in Maple 2015.
