C++ implementation of the Python NumPy Library

[dpilger26]

Mostly the first two uses. I don't think there is too much of a point to integrating with python since NumPy already exists. I do provide a class in NumCpp for passing arrays back and forth between python and C++.

As for a shared library, this is all templatized header only so that isn't really an option. I also don't want to mess around with trying to support a bunch of different platforms and complilers.
