CVS commit by arwalker: 

If we have changed data files then make sure we recalculate any PSDs. If the number of samples if equal to the number of new samples then its safe to assume that the data file was changed, and so we recalculate the PSD. Previously this was not happening and so the PSD would remain the PSD of the old vector data.
