	// think of this as the "constructor" function - returns a GridSpace object
	// so do your init stuff here
	var GridSpace = function (x, y, height) {
	this.x = x;
	this.y = y;
	this.height = height;
	};

	// this of this as sort of the "class definition", define your other functions here
	// be warned though: everything in the prototype is shared between all GridSpace instances!

	# joshuaconner's Ansible Module skeleton
	#
	# This is a skeleton of an Ansible module I've been using to make quick-and-
	# dirty Ansible modules. Just drop the code in `{{ PLAYBOOK_ROOT }}/library`
	# and it will be accessible like any other Ansible module.
	#
	# This is probably not a "best practices" module skeleton, but I'd like it to

	#
	# That's what this is for - it uses the docker API to return all of the running
	# containers on a machine, so if you need to stuff to containers you haven't
