/* DHT test
* A file with a main that runs our DHT for testing.
*
* Compile with: gcc -O2 -Wall -D VANILLA_NACL -o test ../core/Lossless_UDP.c ../core/network.c ../core/net_crypto.c ../core/Messenger.c ../nacl/build/${HOSTNAME%.*}/lib/amd64/{cpucycles.o,libnacl.a,randombytes.o} DHT_test.c
*
* Command line arguments are the ip, port and public key of a node.
* EX: ./test 127.0.0.1 33445 AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
*
* The test will then ask you for the id (in hex format) of the friend you wish to add
