/**
	The AutoreleasePool class is an assistant class for reference-counted 
	object management.

	The Ruamoko standard library implements object management using a 
	reference counting scheme, and sometimes it is useful to create objects 
	that have a limited lifespan. For these objects, it is often useful to not
	have to explicitly free them -- thus the “autorelease” system.

	Autorelease is best described as a “delayed release”, to 
	complement the Object::retain and Object::release methods. It is used 
	when an object is being created on behalf of another object, where the 
	client is not necessarily expected to assume ownership over the object 
	created.
