Description

This project contains an easy-to-use powerful n-dimensional histogram class implemented in C++0x, optimized for convenience and excellent performance under heavy duty. The histogram has a complete C++ and a Python interface, and can be moved over the language boundary with ease. Numpy is fully supported; histograms can be filled with Numpy arrays at C speeds and are convertible into Numpy arrays without copying data. Histograms can be streamed from/to files and pickled in Python.

My goal is to submit this project to the Boost Libraries.
