Added a python branch.  Will work on developing method and then we can rewrite in Julia to get some speed up.
In the middle of building the An sequences.
Merge branch 'master' of github.com:sternSargentRA/Smolyak.jl into Python
BUG: Not totally finished with the python.  Very close, but need to troubleshoot sparse_grid.

CODE: Finished grid.  About to start on constructing basis functions.
CODE: Made some progress on building polynomials.

Added numba. Pure python implementation seems to be working really fast. Possibly broken?
Tried speeding it up. Saw some improvement, but not as much as hoped for.
Python code is catching up to dolo.  One line to fix and it is faster.
smolyak_jmmv2 is now fastest working version that we (and possibly anyone else) have implemented

CLEAN: A couple of visual clean ups.
Removed permute.py and made it a function within the file (also, removed the unnecessary pieces of the code.)
Merge branch 'master' of github.com:sternSargentRA/Smolyak.jl into Python
PMUTE: I think I fixed this function.
Put things in folders and reorganized.  Need to make sure julia code is fully up to date.
