Description
</h2>

<p><CODE>net = glminit(net, prior)</CODE> takes a generalized linear model
<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 similar to that in <CODE>mlpprior</CODE> but for a single layer of
weights, 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).
