Copied @mposa 's jointOffsetCalibration over from DRC. Rewrote his test function; it now creates simulated measurement data and verifies that the offsets, marker positions, and floating states are close to their 'actual' values.
Fixed dumb mistake: didn't update Atlas urdf path after moving test file. Also disabled more warnings.
moved calibration files to robotInterfaces, fixed urdf reference in test
