modifying cc net’s training code

made some modifications to the code today between classes, didn’t have time to do any tests. mathematica 6’s “dynamic” command is very useful for displaying status messages while training (for example, how many nodes have been added, how many iterations through the training set completed, etc). also changed it so when training the outputs it will stop after the error stops changing significantly, rather then just after a set number of iterations of the training set. the file cascnet5.nb has been backed up on euclid.
