+function net = glmunpak(net, w)
+%GLMUNPAK Separates weights vector into weight and bias matrices. 
+%
+%	Description
+%	NET = GLMUNPAK(NET, W) takes a glm network data structure NET and  a
+%	weight vector W, and returns a network data structure identical to
+%	the input network, except that the first-layer weight matrix W1 and
+%	the first-layer bias vector B1 have been set to the corresponding
+%	elements of W.
