Python Equations 1.1 released under BSD license

The middleware code for http://zunzun.com has been released under a BSD license. The project is a collection of Python equations that can fit themselves to both 2D and 3D data sets, output source code in several computing languages and can use an included genetic algorithm for initial parameter estimation. Requires SciPy and SciPy's weave module.
