Detailed Description

Object holding Keplerian orbital elements of a body.

Contains necessary information to determine the orbit of a body. We use the angular momentum and Laplace vector to avoid problems with singular cases (e=0, I=0); the argument of periapsis and the longitude of the ascending node can be computed by calling member functions.
