Initial Submission of ICRF to ITRF transformation
Fix warning.
Add IAU2006 XYS data files generated by Components.
Updating ICRF changes to include V&V Unit Testing

Including hard coded numbers from STK Components
to compare numbers for validation.
Cleaning up ICRF code / Adding Comments

Removed vestigial code and comments, added comments to the code and tests
to indicate the verification work for time standards and the STK
Components test values used in the unit tests.
Add Iau2006XysData class and specs.
Add JulianDate.getDaysDifference method.
Hook up actual XYS data to ICRF transformation.
Merge remote-tracking branch 'origin/master' into icrf
Slightly hacked-up inertial visualization of points and paths.
Fix failing ICRF tests.
Fix test failures and add doc.
Merge remote-tracking branch 'origin/master' into icrf
Updating EarthOrientationData for EOP Interp

Updating EarthOrientationData to include linear interpolation of EOP data
and handling for special cases (interpolating Ut1).  Also updated the
TransformSpec tests now that we are handling more than one hard-coded data
point for EOP.
More inertial path visualization work

DynamicPositionProperty can now store data in both fixed and inertial reference frames.  Some new functions (currently private) are used by the DynamicPathVisualizer to render in the frame that the data is defined in.  Still needs to be updated to always render earth-fixed for 2D and Columbus view and also handle changing reference frames.
Return default EOP data if nothing is loaded.
Hook up EOP to the ICRF <-> ITRF transformation.
Improve tests and error handling for ICRF transformation.
Merge remote-tracking branch 'origin/master' into icrf
Use buildModuleUrl instead of require to resolve XYS files.
