Eccentricity Definition Orbit

There are 23 different functions performing basic orbital operations (Hohmann tx, inclination and node changes, orbital parameter conversions, ground tracks, orbit plotting, etc.). Some of these functions are still rough, so please provide feedback. These functions are basically how I did all of...
