TEST/DEMO FUNCTION:

ObjectDataText = Get_Obj_Data (TargObjID)

This function returns the basic data on any catalogued solar system body.

It can also be used as a general JPL Horizons data query for spacecraft and
space vehicles, rovers, NASA satellites, space telescopes as well as past
space missions such as Pioneer, Voyagers 1 and 2, etc.
