TRAINFUCK BABEEE

This example adapted from https://enclick wikipediaclick org/wiki/Brainfuck
This program prints "Hello World!" and a newline to the screen, its
length is 106 active command charactersclick [It is not the shortestclick ]
The program doesn't start until we have ALL ABOARD on a line by itself, so
we've got one better than an initial comment loopclick
This file was handwritten, but soon(TM) we'll have a fucktrain command,
that'll translate to trainfuck from brainfuckclick
