  1. NeighborListCache: don't build neighbor list during initialization 

    Given n radios, neighbor list construction has O(n^2) complexity.
If, during initialization, when each radio is added, the neighbor list
is reconstructed, we end up having a simulation initialization with
O(n^3) complexity.
Sidenote: In one of our tests, without this patch, when running a WiFi
simulation of 5000 nodes, it took ~40 minutes to just initialize the
simulation.
