Debugging a meteor app with node inspector.

	Client-side you have the console. For server-side debugging, use node-inspector and make sure you have meteor v0.5.3, which makes things easier thanks to support for NODE_OPTIONS:

	Install node-inspector: `npm install -g node-inspector`
	Start meteor: `NODE_OPTIONS='--debug' mrt run`
	Start `node-inspector`
	Go to the URL given by node-inspector in Chrome
	Debug at will
