Tasks:

• See nismod-2 errors on master checkout

• integration tests to pass

• email Ron Fowler at STFC

  The abstract class error looks like the DigitalCommsWrapper hasn't fully implemented the
  SectorModel interface.

The data interfaces for smif have also been changing faster than the sector model prototypes.
Over the next 3-6months each model should be getting to a more mature state and integration
will be a focus over that time.

The configuration errors relate to the scenario data format, which is another area under active
development as Craig Robson (Newcastle) is working on the database backend to have as
alternative option to our first-prototype YAML file inputs.
