+                This object implements the Kalman filter, which is a tool for 
+                recursively estimating the state of a process given measurements
+                related to that process.  To use this tool you will have to 
+                be familiar with the workings of the Kalman filter.  An excellent
+                introduction can be found in the paper:
+                <blockquote>
+                    An Introduction to the Kalman Filter
+                    by Greg Welch and Gary Bishop

+            This object is a tool for doing time series prediction using 
+            linear <a href="ml.html#rls">recursive least squares</a>.  In particular,
+            this object takes a sequence of points from the user and, at each
+            step, attempts to predict the value of the next point.
