Fast Fitting with GPU acceleration

This project, based on an older version of the ''GenCurvefit'' package by Andrew Nelson (https://www.wavemetrics.com/project/gencurvefit),  uses differential evolution algorithm for curve fitting but adds a possibility of GPU acceleration (OpenCL interface via IgorCL XOP, https://www.wavemetrics.com/project/IgorCL) for extremely fast fitting of complex models.  The demo projects included can be used as a starting point to develop your own models.
