This script runs a server (to be accessed using netcat) to run an interactive poll. To use:

1. Create a file vote.yaml that specifies the voting options. See vote.yaml.sample for an example, or the source code for a complete specification of what goes in the file.
2. Run python3 voteserver.py PORT_NUMBER
3. Connect using nc!

To control the server once it is running, use the commands specified in voteserver.py.
