//!  Describes a coordinate system in a plane (2D space). <br>
//! A coordinate system is defined by: <br>
//! -   its origin (also referred to as its "Location point"), and <br>
//! -   two orthogonal unit vectors, respectively, called the "X <br>
//!   Direction" and the "Y Direction". <br>
//!   A gp_Ax22d may be right-handed ("direct sense") or <br>
//! left-handed ("inverse" or "indirect sense"). <br>
//! You use a gp_Ax22d to: <br>
//! - describe 2D geometric entities, in particular to position <br>
//!   them. The local coordinate system of a geometric <br>
//!   entity serves for the same purpose as the STEP <br>
//!   function "axis placement two axes", or <br>
//! -   define geometric transformations. <br>
//! Note: we refer to the "X Axis" and "Y Axis" as the axes having: <br>
//! -   the origin of the coordinate system as their origin, and <br>
//! -   the unit vectors "X Direction" and "Y Direction", <br>
//!   respectively, as their unit vectors. <br>
