//! 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 profile along a spine.
//! 2 - removing the self-intersections.
//!
//! The Profile is expected to be planar and can be a line
//! (which lies in infinite number of planes).
//!
//! 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).
//!
//! The coordinate system is determined by theIsAxeProf argument:
//! - if theIsAxeProf is true, R is the global coordinate system,
//! - if theIsAxeProf 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.
//!
//! theJoinType 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.
//! 
//! if <theIsSolid> is TRUE the Shape result is completed to be a
//! solid or a compound of solids.
//! 
//! If theIsProfOnSpine == TRUE then the profile must connect with the spine.
//!
//! If theIsVolume option is switched on then self-intersections
//! in the result of Pipe-algorithm will be removed by 
//! BOPAlgo_MakerVolume algorithm. At that the arguments
//! "theJoinType", "theIsAxeProf", "theIsProfOnSpine" are not used.
