   Function     :       sinfo_new_slit_pos()
   In           :       ini_file: file name of according .ini file
   Out          :       integer (0 if it worked, -1 if it doesn't) 
   Job          :


  Normal method:

  does the wavelength calibration and the fitting of the slitlet sinfo_edge 
  positions (ASCII file 32 x 2 values) if wished
  produces an array of the bcoefs and of the fit parameters if wished and a 
  wavelength calibration map input is an emission line frame and a line list


  o searching for lines by cross sinfo_correlation with a line list
  o Gaussian fitting of emission lines in each column->positions of the lines->
    resulting fit parameters can be stored in an ASCII file
  o Fitting of a polynomial to the line positions for each column
  o Smoothing: fitting of each polynomial coefficient by another polynomial
    across the whole frame -> resulting polynomial coefficients can be stored 
    in an ASCII file.
  o Wavelength calibration map (micron value for each frame pixel) can be
    produced by using these coefficients and a cross sinfo_correlation to the
    original frame

  o The slitlet sinfo_edge positions can be fitted:
    1) Automatically (not really stable) or by using guess sinfo_edge positions
    2) By using a Boltzmann or a linear slope function

  Slit method:

  does the wavelength calibration and the fitting of the slitlet sinfo_edge 
  positions (ASCII file 32 x 2 values) if wished produces a list of the fit 
  parameters and of the smoothed coefficients if wished and a wavelength 
  calibration map input is an emission line frame and a line list

  o Does the same as other method but smoothes the found polynomial 
    coefficients within each slitlet and not over the whole frame.

  o Produces always a wavelength calibration map and does not crosscorrelate.
