//! Describes functions for computing all the extrema <br>
//! between two surfaces. <br>
//! An ExtremaSurfaceSurface algorithm minimizes or <br>
//! maximizes the distance between a point on the first <br>
//! surface and a point on the second surface. Results <br>
//! are start and end points of perpendiculars common to the two surfaces. <br>
//! Solutions consist of pairs of points, and an extremum <br>
//! is considered to be a segment joining the two points of a solution. <br>
//! An ExtremaSurfaceSurface object provides a framework for: <br>
//! - defining the construction of the extrema, <br>
//! - implementing the construction algorithm, and <br>
//! - consulting the results. <br>
//! Warning <br>
//! In some cases, the nearest points between the two <br>
//! surfaces do not correspond to one of the computed <br>
//! extrema. Instead, they may be given by: <br>
//! - a point of a bounding curve of one surface and one of the following: <br>
//! - its orthogonal projection on the other surface, <br>
//! - a point of a bounding curve of the other surface; or <br>
//! - any point on intersection curves between the two surfaces. <br>
