//! Describes an axis in the plane (2D space). <br>
//! An axis is defined by: <br>
//! -   its origin (also referred to as its "Location point"),   and <br>
//! -   its unit vector (referred to as its "Direction"). <br>
//! An axis implicitly defines a direct, right-handed <br>
//! coordinate system in 2D space by: <br>
//! -   its origin, <br>
//! - its "Direction" (giving the "X Direction" of the coordinate system), and <br>
//! -   the unit vector normal to "Direction" (positive angle <br>
//!   measured in the trigonometric sense). <br>
//! An axis is used: <br>
//! -   to describe 2D geometric entities (for example, the <br>
//!   axis which defines angular coordinates on a circle). <br>
//!   It serves for the same purpose as the STEP function <br>
//!   "axis placement one axis", or <br>
//! -   to define geometric transformations (axis of <br>
//!   symmetry, axis of rotation, and so on). <br>
//! Note: to define a left-handed 2D coordinate system, use gp_Ax22d. <br>
