27 | Implementation: | |
28 | ||
29 | We have chosen to have the histograms as non-persistent meber to | |
30 | allow better debugging. In the copy constructor we then have to | |
31 | assign the pointers to the existing histograms in the copied | |
32 | list. This have been implemented but not tested. | |
