# - Convert a SimplicialComplex containing one of GEOMETRIC_REALIZATION, G_DIM, VOLUME, SIGNATURE
# to GeometricSimplicialComplex, rename the property GEOMETRIC_REALIZATION into COORDINATES.
# - Rename MINKOWSKI_SUMMAND_CONE to MINKOWSKI_CONE
# - Upgrade LATTICE_POINTS to LATTICE_POINTS_GENERATORS
# - Rename TropicalHypersurface<Rational> to Hypersurface<Min>,
# replace the property AMBIENT_DIM with N_VARS
