Renamed example file & added comments

FEAT Barnes-Hut t-SNE

Vectorized the math calls -- 3x faster on neg grad

Draft of n-dimensional barnes-hut; failing tests

Tests pass, error being computed in cython

Added error calculation to pos gradient

Changed cases where points are very close to be clearer

Clearer variable names
