Component to specify that two GSBody objects are in orbit around their mutual center of mass (CM). Use when the mass ratio of the two bodies m1/m2, m1 < m2 is non negligible. e.g. the Earth/Moon system.
The center of mass can be optionally added as GSBody. This is intended for cases where the propagation of the binary bodies is KEPLER mode, in which case they need a center object that is fixed or is itslef in KEPLER mode.
More commonly the bodies will be given the necessary binary orbit (r, v) intial conditions added to the binary CM initial conditions (which could be as RV or an orbit COE).
If the CM is added and a GRAVITY propagator is used, the position of the CM will be computed based on the positions of the binary bodies. This allows it's use as the center of a component to display the orbit wrt the CM.
The binary orbit initial conditions must be specified using a COE. The physical size of the orbit is between the bodies.

| GEBodyState | cmState ) |
(Internal Use) Fill in the BodyInitData for a member of the binary system. Expecting to be called as part of the GSController.BodyAdd() logic.
If the body is part of a binary it needs to have it's gsBinary field set (the editor script will do this, if un-edited need a script to do this).
If the CM is being added, then it can be the center object provided it has been added first and the BID can be a copy of the binary BID (as COE) suitably scaled.
If CM not added then need to compute the absolute R, V including the initial info from the CM BodyInitData.
