/* Messenger test
*
* This program adds a friend and accepts all friend requests with the proper message.
*
* It tries sending a message to the added friend.
*
* If it recieves a message from a friend it replies back.
*
*
* This is how I compile it: gcc -O2 -Wall -D VANILLA_NACL -o test ../core/Lossless_UDP.c ../core/network.c ../core/net_crypto.c ../core/Messenger.c ../core/DHT.c ../nacl/build/${HOSTNAME%.*}/lib/amd64/{cpucycles.o,libnacl.a,randombytes.o} Messenger_test.c
*
*
* Command line arguments are the ip and port of a node (for bootstrapping).
*
* EX: ./test 127.0.0.1 33445
