+Description
+</h2>
+
+<p><CODE>net = netinit(net, prior)</CODE> takes a network data structure
+<CODE>net</CODE> and sets the weights and biases by sampling from a Gaussian
+distribution. If <CODE>prior</CODE> is a scalar, then all of the parameters
+(weights and biases) are sampled from a single isotropic Gaussian with
+inverse variance equal to <CODE>prior</CODE>. If <CODE>prior</CODE> is a data
+structure of the kind generated by <CODE>mlpprior</CODE>, then the parameters
+are sampled from multiple Gaussians according to their groupings
+(defined by the <CODE>index</CODE> field) with corresponding variances
+(defined by the <CODE>alpha</CODE> field).
