Task Title

Task: Test & refine routing function

Task Description

This Task will refine the routing function so that it:

Has an adequate degree of randomness -- add more variability
Avoids searching too many paths (efficiency)
Use a weighted randomness function to shuffle the routers: weight the closest routers MORE HEAVILY
Maintains a roughly consistent radius increment throughout (reducing the # of small and large jumps)
Handles all edge cases Experiment with:
Starting radius increment
Problem: If client & destination are too close, the route will return false <-- radius will be set too large, & return false; test this using VPN -- fix this
Consider performing a weighted shuffle for neighbors, weighted based on:
1. Heuristic: Distance from destination
2. Landing points or routers (prioritize landing points, since they send to a separate continent)
Somehow PRIORITIZE paths for which inner nodes could be found (in LandingPoint route function)
