v0.2 Cleanup, Testing, and Loose Ends

[sambux1]

The bulk of the work for v0.2 is complete, but I won't feel good about finalizing this version until we've dealt with a few final bugs, implemented a few more minor features (mostly for our own convenience), and built out a decent test suite.

I'm listing all the things that we need to get done before closing v0.2 below, and we'll add to this over time until we feel it's good to close.

Comms Testing (Sam)

Node Testing (Ahmed)

System Testing (Ahmed)

Minor Features

• make the Simulator pipes bidirectional to allow nodes to pass output directly to the simulator
• automatically clear leftover data from the last run when starting the system again
• make the test suite easier to run/call
