Travelling between locations

[JosephPB]

Currently people move around the camp without interacting with those along the way. This could be a reasonable assumption in some places, however, it has been found that many streets and roads in the camp are not wide enough to allow social distancing. We should have some way to randomly interact and transit the virus as people move between locations.

People currently know where they are coming and going to at each time step and so, although we could account for a road network, the simplest thing would be to draw a line between the two places and randomly interact with households along the way.

I think what we could do is define which places people generally travel further to get to and have those locations activate a 'travel' class which account for their movement.
