//! The geometric processor package, called gp, provides an

//! . for algebraic calculation such as "XYZ" coordinates, "Mat"
//! matrix
//! . for basis analytic geometry such as Transformations, point,
//! vector, line, plane, axis placement, conics, and elementary
//! surfaces.
//! These entities are defined in 2d and 3d space.
//! All the classes of this package are non-persistent.
