Router for mqtt subscriptions.
This module a router for use with MQTT subscriptions.

I have added a simple override for the topic subscription to enable named params, really this is to avoid the inevitable tokenising of the topic which I do every time I build complex topic structures.
NOTE: I will need to revisit this with some more validation, but for now it works for my simple requirements.
var mqtt =mqttrouter = ;var settings =reconnectPeriod: 5000;// client connectionvar client = mqtt;// enable the subscription routervar router = mqttrouter;// subscribe to messages for 'hello/me'router;// subscribe to messages for 'hello/you'router;// subscribe to messages for 'some/+/you' with a named param for that tokenrouter;
