Some operations for working with []rune
thingies and stuff which may be particularly
useful for things like justifying text, manipulating strings, or just being a dang hunk.
I mostly wrote this to lift it out of tooey
s := []rune(" TEST STRING")
s = ShiftWhiteSpaceRight(s)
> "TEST STRING "
s := []rune("ABCDEF")
s = ShiftLeft(s)
> "BCDEFA"
