//!  Provides general functions to build form features. <br>
//! Form features can be depressions or protrusions and include the following types: <br>
//! -          Cylinder <br>
//! -          Draft Prism <br>
//! -          Prism <br>
//! -          Revolved feature <br>
//! -          Pipe <br>
//! In each case, you have a choice of operation type between the following: <br>
//! -          removing matter (a Boolean cut: Fuse setting 0) <br>
//! -          adding matter (Boolean fusion: Fuse setting 1) <br>
//! The semantics of form feature creation is based on the construction of shapes: <br>
//! -      along a length <br>
//! -      up to a limiting face <br>
//! -      from a limiting face to a  height <br>
//! -      above and/or below a plane <br>
//! The shape defining construction of the feature can be either the <br>
//! supporting edge or the concerned area of a face. <br>
//! In case of the supporting edge, this contour can be attached to a <br>
//! face of the basis shape by binding. When the contour is bound to this <br>
//! face, the information that the contour will slide on the face <br>
//! becomes available to the relevant class methods. In case of the <br>
//! concerned area of a face, you could, for example, cut it out and <br>
//! move it to a different height which will define the limiting face of a <br>
//! protrusion or depression. <br>
//! Topological definition with local operations of this sort makes <br>
//! calculations simpler and faster than a global operation. The latter <br>
//! would entail a second phase of removing unwanted matter to get the same result. <br>
