Order of levels

In the original Kurucz data files for a spectral line always the level with even parity is listed first - regardless of level energy.
In this implementation, however, always the lower level of a transition, i.e. the level with lower energy, is listed first, and second the upper level of this transition.
This seemed to be more appropriate for the needs of us experimentalists.
