+%MLPEVFWD Forward propagation with evidence for MLP
+%
+%	Description
+%	Y = MLPEVFWD(NET, X, T, X_TEST) takes a network data structure  NET
+%	together with the input X and target T training data and input test
+%	data X_TEST. It returns the normal forward propagation through the
+%	network Y together with a matrix EXTRA which consists of error bars
+%	(variance) for a regression problem or moderated outputs for a
+%	classification problem. The optional argument (and return value)
+%	INVHESS is the inverse of the network Hessian computed on the
+%	training data inputs and targets.  Passing it in avoids recomputing
+%	it, which can be a significant saving for large training sets.
