Started adding code to read settings.txt off of SD card. Still need to do something with the missionInfo character array, stick it into the header of the output files.
Added code to include missionInfo in output file headers. Added LED notification of whether settings were successfully read from the SD card (10 green flashes of LED) or not read properly (5 red flashes of ERRLED). It is now possible to set the startMinute and dataDuration parameters, plus some mission info, by including a settings.txt file on the microSD card at startup.
