New commands to handle spectra

We have introduced some new commands to manage spectra:

  • Actions/Spectra/Save simulated spectra as target spectra (stores simulated spectra as target spectra and switches on the display of target spectra at the same time)
  • Actions/Spectra/Flip target and measured spectra (exchanges target and measured spectra – this can be used to fit a model to target spectra)
  • Actions/Spectra/Export/All simulated spectra to VON ARDENNE exsitu file (simply does what its name says)
