Rcpp implementation of NODF nestedness metric, and null model based statistical tests

To build, modify the Makefile for your system and run "make". Currently this is setup to build on Mac with llvm. This requires Rcpp.

The nested_test.R runs this NODF function and the one contained in the vegan R package.

This is under heavy development, and is highly experimental at the moment. In the future, I plan to release this as an R package.

Some preliminary stats on the vegan R package compared with the new NODF function in C
