minfx SVN archive

Updated the release checklist for the new freshmeat layout.

Made the scipy SA annealing import optional.

This allows minfx to be used without installing scipy.

Incorporated the scipy SA code into the generic interface.

Added a package containing a tiny fraction of the scipy (http://www.scipy.org/) package.

This code is distributed under a BSD licence which is included. Currently only the simulated
annealing module scipy.optimize.anneal is included. This packages is temporary until simulated
annealing is directly implemented into minfx.

Bug fix for the grid_point_array() function for when the verbosity arg is greater than 2.

The print out was referencing a non-existent data structure.

Fix for grid_split() for when the number of divisions is more than the total number of points.

The last divisions are discarded in this case.

Added the function grid_point_array() for finding the minimum point in an array of grid points.

This allows for completely non-linear grid searches as each point is arbitrary.

Added support for constraints into grid_split().

Points which violate the constraints are now eliminated prior to the grid subdivision.

Added the grid_split() generator function.

This takes a linear gird, converts it to a linear array of points, and then splits these returning
each grid subdivision.

The optimisation output is more consistent.

The numpy array has been even better formatted.
