Tried adding the custom body example to the approximate_jpl_model() function by adding a cpp code block below the python code block. Check whether this works correctly in the API.
Changed Cartesian state and Keplerian state in constant() and keplerian() examples, to make more sense.
In environment
Added RotationalEphemeris class and the corresponding body_fixed_to_inertial_rotation function. If this works correctly and the pull request is accepted, I can add the other functions corresponding to RotationalEphemeris.
In ephemeris: Fixed spelling mistakes.
