Updated Inline HTTP; new K-Means Clustering code

I've updated Inline HTTP to include, among other features, non-scalar (hierarchical and multi-dimension arrays) GET/POST variables. For example, passing food[]=spam&food[]=eggs now reads the input as an array named food with two elements, spam and eggs.

I also have uploaded k-means clustering code that does proximity clustering. This code is unrestricted open-source code that you can freely modify and use as you see fit.
