#Overview
The idea behind this feature is to allow the users to continue using a similar API to the hub's API while being able to generate MatSim solutions. It would probably look something like:

MatSimEngine(city, tmp_folder)

This requires building a minimum of the following files:

facilities.xml
network.xml
population.xml
config.xml

Facilities

This would be done easily using the already existing buildings. It would probably something like this:

    for building in city.buildings():
      facility = {
        '@id': building.building_id,
        '@x': str(building.centroid[0]),
        '@y': str(building.centroid[1]),
        'activity': {
          '@type': building.function,
          'capacity': {
            '@value': '4.0'
          },
          'opentime': {
            '@day': 'wkday',
            '@start_time': '00:00:00',
            '@end_time': '30:00:00'
          }
        }
      }
      facilities_dict['facilities']['facility'].append(facility)

Things like the function should be mapped. Currently the examples have "home", "work", "secondary" but we can do any we want.

Network

This is TBD but in the documentation we are provided with ways of getting the network of a city using OpenStreetMaps. Might be worth getting Montreal as a whole once and then just querying the nodes/edges we need depending on the facilities.

Population

This one I wouldn't be able to generate properly but we can randomize it.

Config

I have left this for last because there are a ton of parameters that can change. The biggest thing is that it must point to the files we generated but it might have values that we want to let users change.
