I started encapsulating ClientData, and I added the internals for the
heartbeat ssytem. However, when I took a look inside UDPNetworkUtility, I
realized that I didn't have to pass the IPaddresses by reference anymore.
Therefore, I've changed it to accept the addresses by value, and I'm
committing that change right away before I finish the heartbeat system.
This engine is really shaping up, I think.
I'm mostly just testing the waters at this stage, and i've left some debug
code in. There's no way to unload, delete, etc. the accounts, but that
comes later.
