"""
	This is a RESTful interface implemented using Flask micro framework.
	The API is driven by configuration that is organized in terms of the monitoring classes
	
	The API is both restful and websocket/socketio enabled.

	We designed the classes to be reusable (and powered by labels):
	'monitoring-type':
		'class':'<class-name>'
		'config':<labeled-class-specific-configuration>'
