Dynamic neighbour observation #175
Description
In a new PR I implement an observation StaticNeighborObservation that target observation based off of the graph neighbourhood of a postively tested node. One could increase the effectiveness by using a DynamicNeighborObservation method that uses the recent contact network.
On obtaining a postively tested node, one could use the total contact durations of this node with it's neighbours over the past K static network intervals, to order their importance, of how likely it is they are infectious, and therefore their importance of candidacy for testing.
