I implemented a warning that appears in interactive mode
whenever mpfit/lmdif are in use and a fit statistic other than
'chisqr' is evaluated.  For example:

  isis> set_fit_statistic ("cash");
  isis> eval_counts;
   Parameters[Variable] = 6[3]
              Data bins = 1024
  *** Warning:  mpfit/lmdif optimize chi-square only.
             Cash Statistic = 973.3915
     Reduced Cash Statistic = 0.9533707

The warning cannot be turned off.

An updated isis tar file is available on the web page and the
git repository has been updated.

Thanks,
-John
