Detailed Description

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 <br>

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.
