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 datwrite(filename, x, t)
+%DATWRITE Write data to ascii file.
+%
+%	Description
+%
+%	DATWRITE(FILENAME, X, T) takes a matrix X of input vectors and a
+%	matrix T of target vectors and writes them to an ascii file named
+%	FILENAME. The file format is as follows: the first row contains the
+%	string NIN followed by the number of inputs, the second row contains
+%	the string NOUT followed by the number of outputs, and the third row
+%	contains the string NDATA followed by the number of data vectors.
+%	Subsequent lines each contain one input vector followed by one output
+%	vector, with individual values separated by spaces.
