wolffd@0: %	Description
wolffd@0: %	CONFFIG(Y, T) displays the confusion matrix  and classification
wolffd@0: %	performance for the predictions mat{y} compared with the targets T.
wolffd@0: %	The data is assumed to be in a 1-of-N encoding, unless there is just
wolffd@0: %	one column, when it is assumed to be a 2 class problem with a 0-1
wolffd@0: %	encoding.  Each row of Y and T corresponds to a single example.
wolffd@0: %
wolffd@0: %	In the confusion matrix, the rows represent the true classes and the
wolffd@0: %	columns the predicted classes.
wolffd@0: %
wolffd@0: %	FH = CONFFIG(Y, T) also returns the figure handle FH which  can be
wolffd@0: %	used, for instance, to delete the figure when it is no longer needed.
