public class Inlist<T extends Inlist<T>>
extends java.lang.Object

Utility class for making poolable objects. Instead of using an additional list to hold pool items just extend this class.

Also handy for objects that exist in only *one list* at a time, if you are *REALLY* sure about it. Better do not use it! :)
