Indexing implemented and tested (via labels)  Need to check plots.
DBSCAN Indexing Tests Complete.  Also moved parallellization inside DBSCAN.
BDT Testing Phase
BDT implemented and Tested to be ~90% accurate for N_min_sigma=3.  Need to test N_min_sigma=4.\n  Indexing is very fast for distance calculation, but cluster expansion is still slow.
Fixed DBSCAN issue with empty eps-neighborhood.
More BDT info to ipython notebook. Next is adding spherical grid indexing and ident 0-360.
Implemented Spherical DBSCAN and fixed indexing bug.  Spherical DBSCAN not currently working correctly -> needs fixin
Spherical DBSCAN working.  Also added adaptive grid indexing.  Efficiency increase of 100% on 1M events.
Added BG template tools.
Added BGTools.py
