Renamed the test package to simulations
Created a simulations interface

Deleted exact copied files of Kademlia from the following packages:
- kademlia.simulations

SocialKademlia is a copy of the Kademlia (github.com/joshuakissoon/kademlia)  project, many classes are just copied
Problem: When we make a change to Kademlia, we need to copy over that change to socialKad; Solution: Now I'm referencing Kademlia in SocialKad, and only let SocialKad contain the updated files
