Log message:
    Finished the Between patch Christopher started.

    Implements between (symmetric / asymmetric) as a node.

    Executes the left or right expression once, makes a Const out of the
    resulting Datum and executes the >=, <= portions out of the Const sets.

    Of course, the parser does a fair amount of preparatory work for this to
    happen.
