Distributed auto-healing droplets using simple server group configurations.

Healthcare.js creates a fully distributed auto-healing system to DigitalOcean setups. Simply define groups by tags and provide configs for creation of those servers. Using UDP unicast, health checks will determine when a server in the group has gone down and it will be destroyed and replaced using the given config. No need for single points of failure or additional servers to manage as healthcare.js runs on each server in the pool as a standalone Node.js service.
