//!  Provides functions for basic geometric computation on <br>
//! elementary surfaces. <br>
//! This includes: <br>
//! -   calculation of a point or derived vector on a surface <br>
//!   where the surface is provided by the gp package, or <br>
//!   defined in canonical form (as in the gp package), and <br>
//!   the point is defined with a parameter, <br>
//! -   evaluation of the parameters corresponding to a <br>
//!   point on an elementary surface from gp, <br>
//! -   calculation of isoparametric curves on an elementary <br>
//!   surface defined in canonical form (as in the gp package). <br>
//!  Notes: <br>
//! -   ElSLib stands for Elementary Surfaces Library. <br>
//! -   If the surfaces provided by the gp package are not <br>
//!   explicitly parameterized, they still have an implicit <br>
//!   parameterization, similar to that which they infer on <br>
//!   the equivalent Geom surfaces. <br>
