Typecasting (Including Single-Argument Constructors)

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 Section for 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.
