Debug Statements in Server

[nVitius]

There's an npm package that allows for debug output that can be displayed or hidden using an environment variable: https://www.npmjs.com/package/debug

It might be useful to add some debug statements throughout the server code for bug reports and the like. What do you think, @jfurrow?

I had the idea after reading this comment in another issue: #320 (comment)

Yep, this is a great idea!
