Typecasting (Including Single-Argument Constructors)

AVectorEC(GeOb& a)

Used to convert an arbitrary geometric object to an affine vector equivalence class. Standard maps will be used to map the GeOb to a affine vector equivalence class; this will succeed if the mapping succeeds.

AVectorEC(MultiMap& m)
AVectorEC(Map& m)

See the descriptions given in Section for the GeOb
single-argument constructors. If m can be cast into an affine vector, these constructors will then attempt to map it to an affine vector equivalence class.
