Parallelization

[amirsani]

Great package!

Have you looked into using joblib on this loop,
for i, (feat1, feat2) in enumerate(feature_tuples)
in feateng.py?

Seems like it could be easily parallelized. You have several global variables inside the loop, so I haven't had a chance to deconstruct this into a function that could be called via joblib. I thought it might be more straightforward for you as you are more familiar with the code.
