BNW using Octave instead of Matlab.

This version of BNW should perform the same as the original version. The only difference is that it uses Octave instead of Matlab when running BayesNet Toolbox during parameter learning.

I am calling this BNW_1.02. It can be accessed at:
compbio.uthsc.edu/BNW_1.02

+function g = netderiv(w, net, x)
+%NETDERIV Evaluate derivatives of network outputs by weights generically.

+%	Description
+%
+%	G = NETDERIV(W, NET, X) takes a weight vector W and a network data
+%	structure NET, together with the matrix X of input vectors, and
+%	returns the gradient of the outputs with respect to the weights
+%	evaluated at W.
