[Ops] Comparison of Cone Search Validator tests

[Tom McGlynn (NASA/GSFC Code 660.1)]

I've just uploaded a comparison of the tests that the various validation 
services perform on Cone Search services.
Note that this is not a comparison of the results, but of what the 
validators are doing and enables us to compare the results from one 
validator to another.

  The document is available at

A similar document should be available soon for SIA tests.
