Expose ECI position, velocity, solar vector, and add beta_angle calculation.

jordanano commented 8 years ago

Description:

expose the calculated ECI (inertial coordinate frame) values for object position, object velocity, Sun Vector in the observation disctionary returned from a predict.observe(..) call
add a beta-angle calculation and expose it in the same observer dict
