gets commuting rate for each individual node (hence it's for individual nodes) Considers a commuting proportion of 11
disnet_comm1(j, edges_subset, i, N_c)
| j | all the nodes `i` is connected to |
|---|---|
| edges_subset | subset of `nd_edges` with all outgoing edges of `i` |
| i | the node for which commuting proportion is being calculated |
| N_c | The commuting proportion of the entire population. Default = 0.11 from Simini |
