Don Cross 22002ab9ce C BaryState: first version, test in progress.
Implemented the C function Astronomy_BaryState().
Used JPL Horizons to generate some test data.
Started work on the C unit test for BaryState,
but it is not yet finished. This is just a good
checkpoint for this work in progress.

Data for testing barycentric state calculation.

This JPL Horizons data is for testing calculation of the barycentric state (position and velocity vectors) using the Astronomy Engine BaryState function. There are test files for all the supported bodies. The files use varying start time, stop time, and time step values, but they are otherwise configured the same.

As an example, here is the batch data for generating Sun.txt:

CENTER= '500@0'
