Functionality list

• Create a GUI for the focus of the spectrograph. At the moment, we are running: SpecFocus.focus_loop from the console.
• Add the option to do multiple exposures on the Fourshot GUI. It will allow to go deeper by stacking images.
• Make the logs to be 'rolling'. Directing to another log file passed midnight.
• For the 'Fourshot', fix the timing between the movement of the telescope and the exposure. The exposure shall start only after the telescope has been moved.
• For the 'Fourshot', make sure there are no errors for short exposures (1 or 2s).
• Add field called 'INSTRUME' and 'TELESCOP' to the fits headers.
• Display somewhere the status of the shutter. At the moment our only guide is the elapsed exposure time.
