Moved to google Code, see http://code.google.com/p/pythonequations/downloads/list

Added fit statistics; also updated GA parameters

Corrected offset forms of equations

Converted numpy warnings to exceptions for trapping

Using scipy's weave module for performance
Tuned genetic algorithm parameters by exhaustive search

Corrected typographical errors in 2D Polynomials and 3D Polyfunctionals

Removed unused code

Corrected typographical error in SimpleExponential2D
Added minor variables to base class

Added 1D data parsing

Added 3D Full Polynomial equations.

- reduced data cache generation bug corrected
- genetic algorithm parameters tuned
- removed a few extraneous semicolons from Python and SCILAB code generators

Removed requirement for C++ compiler.
Removed requirement for weave.

Only dependencies are python, numpy and scipy - now 100% pure Python!

Improve weave import
change all gcc flags to '-O2' fixing 64-bit compilation errors
Correct some minor code generation errors

Maintenance release:

1) updated the base class import statements
2) fixed a bug in the C++ for Standard Vapor Pressure
3) added Gary Cler's Custom Equation

Corrected typographical errors in the 3D example

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.
