34//! This class implements the following algorithms used to
35//! create Hyperbola from Geom2d.
36//! * Create an Hyperbola from two apex and the center.
37//! Defines the main branch of an hyperbola.
38//! The parameterization range is ]-infinite,+infinite[
39//! It is possible to get the other branch and the two conjugate
40//! branches of the main branch.

53//! The major radius is the distance between the Location point
54//! of the hyperbola C and the apex of the main Branch (or the
55//! Other branch). The major axis is the "XAxis".
56//! The minor radius is the distance between the Location point
57//! of the hyperbola C and the apex of the First (or Second)
58//! Conjugate branch. The minor axis is the "YAxis".
59//! The major radius can be lower than the minor radius.
