Today:
	1.  Problem from last time:  
		a.  locations in both loaded_object and gameobject
		b.  jerky elevator movement:  race condition + move from movement thread
	2.  Detaching when moving off something
	3.  Nit:  Resizing (grab from some other demo)
	4.  Nit:  Hide mouse cursor
		glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_DISABLED)		 
	5.  Collisions on the side of things, for the player
	6.  We won't get this far, but if we do, here's another list!

Other stuff on the "soon" TODO list:
	Some kind of projectile we can launch
	Improve the Makefile
	Organize our code
