Neural Nettwork (ANN) Extension

[litdev]

A couple of notes regarding ANN extension, if anyone is interested in maybe using this extension for something more serious.

1] The inputs and outputs both need to be normalised to be between 0 and 1.
2] Corrected a couple bugs (using text training data, 2 issues) and added option to set non-binary output - need to update using extension manager.

Here is my test code (a little tougher than XOr training, but not so much really), averaging 2 integers between 1 and 100, ZWWL934.000.

Results running 10 tests using ANN after traning with 10000 data points, the ANN results are in brackets.
