//! Class to make revolved sweep topologies.
//!
//! a revolved sweep is defined by :
//!
//! * A basis topology which is swept.
//!
//! The   basis topology  must   not  contain solids
//! (neither composite solids.).
//!
//! The basis topology  may be copied  or  shared in
//! the result.
//!
//! * A rotation axis and angle :
//!
//! - The axis is an Ax1 from gp.
//!
//! - The angle is in [0, 2*Pi].
//!
//! - The angle default value is 2*Pi.
//!
//! The result is a topology with a higher dimension :
//!
//! - Vertex -> Edge.
//! - Edge   -> Face.
//! - Wire   -> Shell.
//! - Face   -> Solid.
//! - Shell  -> CompSolid.
//!
//! Sweeping a Compound sweeps  the elements  of the
//! compound  and creates    a  compound with    the
//! results.
