 //! This class implements the following algorithms used
 //! to create a Plane from gp.
 //! * Create a Pln parallel to another and passing
 //! through a point.
 //! * Create a Pln passing through 3 points.
 //! * Create a Pln by its normal.
 //! Defines a non-persistent plane.
 //! The plane is located in 3D space with an axis placement
 //! two axis. It is the local coordinate system of the plane.
 //!
 //! The "Location" point and the main direction of this axis
 //! placement define the "Axis" of the plane. It is the axis
 //! normal to the plane which gives the orientation of the
 //! plane.
 //!
 //! The "XDirection" and the "YDirection" of the axis
 //! placement define the plane ("XAxis" and "YAxis") .
