RVOrbGen:

 Generate an orbit by propagating Keplerian elements. 
 The orbit may have any eccentricity, including parabolic or hyperbolic.

 If t is not entered it generate one orbit. If there are no arguments it
 will plot the orbit. Enter rPlanet to draw a planet sphere. If the sun 
 vector is entered as well the planet sphere will be illuminated.
