+Description
+</h2>
+<CODE>net = knn(nin, nout, k, tr_in, tr_targets)</CODE> creates a KNN model <CODE>net</CODE>
+with input dimension <CODE>nin</CODE>, output dimension <CODE>nout</CODE> and <CODE>k</CODE>
+neighbours.  The training data is also stored in the data structure and the
+targets are assumed to be using a 1-of-N coding.
+
+<p>The fields in <CODE>net</CODE> are
+<PRE>
+
+  type = 'knn'
+  nin = number of inputs
+  nout = number of outputs
+  tr_in = training input data
+  tr_targets = training target data
