Update README.md
Merge branch 'master' of github.com:sternSargentRA/Smolyak.jl
JL: still buggy. don't have time to fix now

For some using the pmute function doesn't work. We get the right number
of points, but they are not in the correct columns.
CLN: Just added some notes and cleaned things up in julia
JL: Julia now works (and wins!)
Adding the Ipython notebook for python.
Python: Cython is not working, but whatever it is doing is fast...
ENH: fixed pmute function to copy elements instead
JL: new smol_inds function TAG: allocate-fill grid

also, tried to write new function for sgrid_2 that pre-allocates and
fills instead of doing the vcat, but it was slower and used more memory

This is a commit to store it for later, in case for some reason we want
it
PYTHON: Added some modifications.  The python version now returns a list (dont know if we need array or not) and is similar in speed to julia.
Python: Played a little with different cartesian methods and such.  We think this is the optimal set of calls.
Python: Working on implementing the building of B.

PY: naive build B method
PY: Working on clever hack to shorten the build B time.  Created new file to hold progress, smolyak_alt.py
JL: updated SGrid type
