Finished the Between patch Christopher started.

Browse Source 
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.
