Read the society's edge list as a symmetric agents-by-agents 0/1 matrix:
entry [i, j] is 1 when agents i and j are connected (an edge exists
in either direction), 0 otherwise. Row and column names are agent ids. This
is the "who could see whom" structure the network encodes, separate from what
any given round actually showed each agent.
