1st Loop namespace and functions created

If no design mission can be found yet, a 1st loop version of mission analysis is run. Only the following values are written in that mode:

• range (which is equal to the required range)
• loaded_mission_energy/mission_energy
• in_flight_energy/trip_energy
• taxi_energy/taxi_out_energy
• taxi_energy/taxi_in_energy

Please check if we can get into the next loops with this solution
