* <b>muse_wave_plot_column</b>: Plot wavelength calibration for one CCD column.
*
* Debug wavelength calibration issues using a graphical representation of the
* wavelength solution for a single CCD column using data written into the tables
* WAVECAL_TABLE and WAVECAL_RESIDUALS by the muse_wavecal recipe.
*
* <b>Command line arguments:</b>
* - <tt>-n nifu</tt> (optional, default: load first FITS extension with data)\n
* IFU/channel number to use
* - <tt>-s slice</tt> (optional, default: 0 = all slices)\n
* slice number for plotting, plots the central column of the slice
* - <tt>-i iteration</tt> (optional, default: 0 = last iteration)\n
* iteration to plot
* - <tt>-c column</tt> (optional, default: 0 = all slices)\n
* CCD column to plot
* - <tt>-r</tt> (optional)\n
* plot residuals rather than absolute values
* - <tt><b>WAVECAL_TABLE</b></tt>\n
* the filename of the wavelength calibration file to use
* - <tt><b>WAVECAL_RESIDUALS</b></tt>\n
* the filename of the wavelength calibration residuals file to use
*
* <b>Return values:</b>
* - <tt> 0</tt>\n Success
* - <tt> 1</tt>\n no filename given

* - <tt> 6</tt>\n argument <tt>-n</tt> with invalid IFU number
* - <tt> 9</tt>\n unknown option given
* - <tt>10</tt>\n residuals table could not be loaded from file
* - <tt>11</tt>\n file does not seem to contain a MUSE residuals table
