Overview

This is a FIFO Hash. Why do I want a FIFO hash? For eroding configurations, of course!!! Just kidding. This is to keep large dictionaries limited to often-used values. When all the values can be calculated anyway, but a dictionary runs the risk of growing too large, this keeps the dictionary in check.
