      ## CHANGE LOG ##
      1.0.0.0
      - Initial version
      
      1.1.0.0
      - Upgraded to v1B00 of the IM.
      - Re-classified this dictionary as a Discipline Dictionary, instead of Mission Dictionary.
      - Renamed Orbital_Mission_Information to Orbital_Mission, Surface_Mission_Information to Surface_Mission
      
      1.2.0.0
      - Upgraded to v1D00 of the IM.
      - Add instrument_clock_start and allow helicopter use case.
      - Add instrument_start_time. This is instrument_clock_start converted to UTC.
      - Updated the definition for start_sol_number to allow a primary sol to be 
        defined for mosaic products inplace of the actual starting sol value.
       
      1.3.0.0
      - Upgraded to v1E00 of the IM
      - Add year_number, year_number_reference attributes to Surface_Mission
      - Added Observation_Context class and attrbitues active_flight_computer, active_flight_imu under Mission_Information

      1.3.0.2
      - add instrument_clock_stop and instrument_stop_time
      - mission_phase_name and mission_phase_identifier to unbounded (multi)

     1.3.0.3
     - add ephemeris_start_time and ephemeris_stop_time to have available at the mission level.
         We do understand et_start and et_stop are also available from the nucspec dictionary but
         this is required by THEMIS which is not a nucspec instrument.

     1.3.1.0
     - add orbit_identifier to Orbital_Mission class.
     
     1.3.2.0
     - Add Observation_Description class
