Extract generated data from simulation experiment

[brianok77]

Extract generated data from the simulation experiment code (https://github.com/covid19-model/simulator) into JSON files. We should have 4 sets of data: (a) a list of sites (Site nodes), (b) a list of people (Device nodes), (c) the "time" each person visited each site (Scan edges), and (d) the "time" each person got their test result back. Jeremy Silver did some initial investigation into this and should be able to provide his thoughts on how we can create this.

As part of this exercise, the simulation code assigned a "risk weight" to each "type of site" (Educational, Social, Transportation, Work, Groceries}. Please extract this "type of site" and weight into the "site nodes" export for future information although the zerobase API may not support it at this time.
