Alex ip/datacube dependencies

Copyright notices added to all code
EOtools.blrb.py & EOtools.bodies.vincenty.py refactored from ga-neo-landsat-processor
Unit tests added (TODO - diagnose failure of Exception2 test in test_tiling.py)
Imports and module paths corrected

N.B: These changes will need to be applied to the open-source repository before the AGDC code can be open-sourced, since the release candidate AGDC now references shared modules from EOtools instead of ULA3.
