Planned Features

1. Use effective area file to present spectra in physical units.
2. Return total counts or flux instead of peak counts in line fits.
3. Allow variable abundances, rather than only Anders & Grevesse values.
4. Allow user-selected label colors, sizes, fonts.
5. Store results of fits to a latex file.
6. Allow plots to be output as QDP files.
7. Make the XSTAR database work more like the ATOMDB database, so that atomic data are available.
8. Allow a wider range of axis units, such as nm or inverse cm.
9. Include undo feature.
10. Improve fitting to allow more options.
