+%GLMEVFWD Forward propagation with evidence for GLM
+%
+%	Description
+%	Y = GLMEVFWD(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.
