Essentially, a Humix-Sense module communicate with other modules and the local controller using NATS-based pub/sub messaging modol : each module provide the information it collects by publishing 'event', while it also listen for 'command' to trigger actions the module supports.

This nodejs module provides an event-driven model to facilitate the creation of Humix-Sense modules. Basically, you need to proivde a config to specify

1. the name of the module
2. the commands the module accepts
3. the event the module generates
4. any child process the module depends upon ( optional )
