Trying to use a transform binding instead of a computed property

	App.ticketsController = Em.ArrayController.create({
	content: Em.A();
	});


	App.backlogController = Em.ArrayController.create({
	contentBinding: Em.Binding.transform(function(value, binding) {
	return value.filter(function(item, index, enumerable) {
	return (item.get('assigned') == undefined);
	});

Possible solution for place mutation (somewhat functional approach)

	# in board initialize
	lookup = PlaceLookup.new
	lookup.add Buildable.new, Coord.new(3, 4) # coords would be calculated from land hexes

	# later
	player = Player.new
	PlaceLookup.build_at player, Coord.new(3, 4)
	PlaceLookup.at Coord.new(3, 4) # => Settlement.new

	The PlaceLookup mutates behind the scenes. So potential impl of #build_at is

Oh the conditionals!

	This example is not my real app, but it's modeled pretty closely to it.

	My mom schedules a couple hundred employees at a local warehouse. In their
	system, a worker can earn "points" for being late or missing shifts. Here
	we have a sort of summary screen for my mom, who may need to follow up with
	new employees or discipline employees with concerning levels of points.

	Questions that arise as I code something like this:
	- Which objects deserve presenters?
	- Should I allow HTML in my presenters?
