//! Provides functions for basic geometric computations on <br>

//! This includes: <br>
//! -   calculation of a point or derived vector on a 2D or <br>
//!   3D curve where: <br>
//!   -   the curve is provided by the gp package, or <br>
//!    defined in reference form (as in the gp package), <br>
//!    and <br>
//!   -   the point is defined by a parameter, <br>
//! -   evaluation of the parameter corresponding to a point <br>
//!   on a 2D or 3D curve from gp, <br>
//! -   various elementary computations which allow you to <br>
//! position parameterized values within the period of a curve. <br>
//!  Notes: <br>
//! -   ElCLib stands for Elementary Curves Library. <br>
//! -   If the curves provided by the gp package are not <br>
//!   explicitly parameterized, they still have an implicit <br>

//!   for the equivalent Geom or Geom2d curves. <br>
