	Order of keys is now the order in which they were added.  This now
	bypasses the normal way of generating keys of a hash.

	Added support for autoflushing.  Initialization can now also be done
	by just specifying a hash ref.  More tests, including something of a
	performance test: on my MacBook it does ~110K new ID's / second and
	about ~400K existing ID's / second using the optimized ro_hash
