Orbit Utilities header file
---------------------------
This file contains orbit utilities for converting between "classical"
keplerian orbital elements and xyz cartesian position and velocity.
 
TODO: Protect edge cases in these files. Right now they only work for 
elliptical orbits
 
The converters in this file are based on those found in Vallado's 
Fundamentals of Astrodynamics and Applications, fourth edition, Chapter
2.5. The test cases are drawn from that text as well.
