Copy the octant functions needed for vector frames
Add modified script for output vector frames
Add test and reference data to make sure we are correctly computing vectors
Tidy up test file
Move test into tests/ dir
Throw out some of the plot related code
Test all 'ref_' files
Further paring and cleanup of vector_frame.py
Seed RNG when running script directly
Update vector_animation to use octant_lite
Add some more reference files for testing
Better test file detection
Accidently turned NFRAMES down. Turning back up again.
Move library code into tabs package
Add flask route for thredds data
Merge branch 'master' into enh/serve-vector-frame

Conflicts:
	app.py
Maintain the THREDDS connection between frequent calls
Use numpy rounding instead of simplejson.encoder.FLOAT_REPR
Use THREDDS for the first frame... gently
Rename mch_animation -> THREDDSVectorFrameSource
