isLatticePolytope -- checks if a polyhedron is a lattice polytope

Description

isLatticePolytope can only be applied to polytopes, i.e. compact polyhedra. It simply checks if it is compact and all vertices are lattice points. 
i1 : P = polyhedronFromHData(matrix{{2,0},{0,-3},{-3,0},{0,2}},matrix{{1},{1},{1},{1}})

o1 = P

o1 : Polyhedron
 
i2 : isLatticePolytope P

o2 = false
 
i3 : P = polyhedronFromHData(matrix{{2,0},{0,-3},{-3,0},{0,2}},matrix{{4},{6},{3},{6}})

o3 = P

o3 : Polyhedron
 
i4 : isLatticePolytope P

o4 = true

Ways to use isLatticePolytope:
