For production usage, shouldn't print to serial port

[ysyyork]

There are a lot of code directly call Serial.print. This will destroy the business logic for anyone using Arduino serial port to communicate. Should add DEBUG flag to conditionally print these information

That's a great point - something I've done in the past, but forgot to include this time. I'll be honest, not sure when I'll get around to adding that, but I'll try to remember next time I tinker with the code.
