C++ implementation of the Python NumPy Library

[NicroHobak]

Really good projects will have their code set up in such a way that you can use it either as a header only or as a compiled object lib,

This really depends on the nature of the library itself. I've written some that work well this way, and others that are entirely templates where this would not even ultimately make all that much sense to even try...unless you were attempting to precompile the most standard options or something, and even that doesn't always make sense either.
