			** This provides the notion of a "critical parameter"
			*** That is, one of the attributes of the simulation has the potential to cause radically different behavior based on its value
			**** See the "10x{40..70}%" graph in the "Example Graphs" section of the Lab Information below for an example of Density exhibiting this behavior.
