Fitbauer main window

Fitbauer reproduces NORMOS and reads and writes its .JOB files. The physics has been contrasted on 411 synthetic spectra and on 564 real fits made with the original program: in 355 of 503 comparable jobs (71 %) it matches or improves on its reduced χ². See NORMOS (.JOB) and the validation reports.
