To test this software, first run:

javac -d ../out src/config/*.java src/remote/*.java src/service/*.java src/node/*.java src/message/*.java

In your terminal to compile all the necessary java classes. Then, run

java -cp ../out remote.Main 127.0.0.1 8081 127.0.0.1:8080

To specify the address and portname of the initial node, and none for the second node (since this is just the initial node we are adding, no other node is currently in the system)
This should then start up a new node, and you will start seeing output for it.
To add another node, open a new terminal and run

java remote.Main 127.0.0.1 <new_port_name> <target_address_and_portnumber>

This will then start up a new node instance that points the existing node as a target instance, and they will then begin communicating
You can repeat this process to add as many nodes as you please.
