Describes a circle in the plane (2D space).
//! A circle is defined by its radius and positioned in the
//! plane with a coordinate system (a gp_Ax22d object) as follows:
//! - the origin of the coordinate system is the center of the circle, and
//! - the orientation (direct or indirect) of the coordinate
//! system gives an implicit orientation to the circle (and
//! defines its trigonometric sense).
//! This positioning coordinate system is the "local
//! coordinate system" of the circle.
//! Note: when a gp_Circ2d circle is converted into a
//! Geom2d_Circle circle, some implicit properties of the
//! circle are used explicitly:
//! - the implicit orientation corresponds to the direction in
//! which parameter values increase,
//! - the starting point for parameterization is that of the "X
//! Axis" of the local coordinate system (i.e. the "X Axis" of the circle).
//! See Also
//! GccAna and Geom2dGcc packages which provide
//! functions for constructing circles defined by geometric constraints
//! gce_MakeCirc2d which provides functions for more
//! complex circle constructions
//! Geom2d_Circle which provides additional functions for
//! constructing circles and works, with the parametric
//! equations of circles in particular gp_Ax22d
