VectorEC(GeOb& a)
Used to convert an arbitrary geometric object to a vector equivalence class. Standard maps will be used to map the GeOb to a vector equivalence class; this will succeed if the mapping succeeds.
VectorEC(MultiMap& m) VectorEC(Map& m)
See the descriptions given in Sectionfor the GeOb
single-argument constructors. If m can be cast into a vector, these constructors will then attempt to convert it to a vector equivalence class.
