OLEB_Queue

public protocol OLEB_Queue

This was taken straight from the objc.io book “Advanced Swift.” It’s so damn useful, that I have it made into a standard tool.

The original design was done by Ole Begemann and Chris Eidhof. I have modified it slightly; but not much.

It is fast as all git-go.
