+            This is a function for solving non-linear least squares problems.  It uses a method
+            which combines the traditional Levenberg-Marquardt technique with a quasi-newton
+            approach.  It is appropriate for large residual problems (i.e. problems where the
+            terms in the least squares function, the residuals, don't go to zero but remain
+            large at the solution)
