//! Describes functions to build evolved shapes.
//! An evolved shape is built from a planar spine (face or
//! wire) and a profile (wire). The evolved shape is the
//! unlooped sweep (pipe) of the profile along the spine.
//! Self-intersections are removed.
//! A MakeEvolved object provides a framework for:
//! - defining the construction of an evolved shape,
//! - implementing the construction algorithm, and
//! - consulting the result.
//! Computes an Evolved by
//! 1 - sweeping a profil along a spine.
//! 2 - removing the self-intersections.
//!
//! The profile is defined in a Referential R. The position of
//! the profile at the current point of the  spine is given by
//! confusing R  and the local  referential given by (  D0, D1
//! and the normal of the Spine)
//!
//! If the Boolean <AxeProf> is  true, R is  O,X,Y,Z
//! else R is defined as the local refential at the nearest
//! point of the profil to the spine.
//!
//! if <Solid> is TRUE the Shape result  is completed to be a
//! solid or a compound of solids.

  //! These constructors construct an evolved shape by sweeping the profile
  //! Profile along the spine Spine.
  //! The profile is defined in a coordinate system R.
  //! The coordinate system is determined by AxeProf:
  //! - if AxeProf is true, R is the global coordinate system,
  //! - if AxeProf is false, R is computed so that:
  //! - its origin is given by the point on the spine which is
  //! closest to the profile,
  //! - its "X Axis" is given by the tangent to the spine at this point, and
  //! - its "Z Axis" is the normal to the plane which contains the spine.
  //! The position of the profile at the current point of the
  //! spine is given by making R coincident with the local
  //! coordinate system given by the current point, the
  //! tangent vector and the normal to the spine.
  //! Join defines the type of pipe generated by the salient
  //! vertices of the spine. The default type is GeomAbs_Arc
  //! where the vertices generate revolved pipes about the
  //! axis passing along the vertex and the normal to the
  //! plane of the spine. At present, this is the only
  //! construction type implemented.
