| * Routine to find maximum and minumum content of a hisogram. |
| * Need GSL library and header. |
| * Contains the routines: |
| * gsl_histogram_max_val find max content values |
| * gsl_histogram_min_val find min content values |
| * gsl_histogram_bin_max find coordinates of max contents bin |
| * gsl_histogram_bin_min find coordinates of min contents bin |
