+       * linreg.c (pspp_linreg): Accept a struct design_matrix.  Use new
+       accessor functions pspp_coeff_get_mean, pspp_coeff_get_sd.  New
+       functions pspp_linreg_get_indep_variable_mean,
+       pspp_linreg_set_indep_variable_mean,
+       pspp_linreg_get_indep_variable_sd,
+       pspp_linreg_set_indep_variable_sd. Altered pspp_linreg_get_coeff
+       to use accessor function pspp_coeff_var_to_coeff.

+       * coefficient.c: New functions pspp_coeff_get_mean,
+       pspp_coeff_set_mean, pspp_coeff_get_sd, pspp_coeff_set_sd,
+       pspp_coeff_var_to_coeff. Added doubles to hold mean and standard
+       deviation in struct varinfo.
