I've now added the data type **hyperbola** to the 3DLDF language.
It corresponds to the type **class Hyperbola** in the C++ code.

The 3DLDF code for generating the following image is in hyprb_00.ldf. TeX code for the including it is in hyprb_00.txt.

The intersection points of a **hyperbola h** and a **path p**,
such that **h** and **p** are coplanar, and the slope of
**p** is finite and non-null.

operator.
