Add further task-specific params to TXT output file

[skrakau]

• I changed def Double to Double, because def is for variables of unknown type
• added the remaining task-specific params to the CO2Record class and added helper function for conversions
• changed some Floats to Doubles to avoid conversion artefacts when converting them to Doubles (when adding to the list). I would suggest we systematically change the structure afterwards (not assigning those floats to List<Double> anymore) and adjust all types to floats where possible.

I just added the parameters, we should think about restructuring and cleaning up a bit in the near future, when the content is more complete.
