//! Describes a branch of a hyperbola in the plane (2D space). <br>
//! A hyperbola is defined by its major and minor radii, and <br>
//! positioned in the plane with a coordinate system (a <br>
//! gp_Ax22d object) of which: <br>
//! -   the origin is the center of the hyperbola, <br>
//! -   the "X Direction" defines the major axis of the hyperbola, and <br>
//! -   the "Y Direction" defines the minor axis of the hyperbola. <br>
//!   This coordinate system is the "local coordinate system" <br>
//! of the hyperbola. The orientation of this coordinate <br>
//! system (direct or indirect) gives an implicit orientation to <br>
//! the hyperbola. In this coordinate system, the equation of <br>
//! the hyperbola is: <br>
//! X*X/(MajorRadius**2)-Y*Y/(MinorRadius**2) = 1.0 <br>
//! The branch of the hyperbola described is the one located <br>
//! on the positive side of the major axis. <br>
//! The following schema shows the plane of the hyperbola, <br>
//! and in it, the respective positions of the three branches of <br>
//! hyperbolas constructed with the functions OtherBranch, <br>
//! ConjugateBranch1, and ConjugateBranch2: <br>
