Announcing phase 2: function operators

Now, with phase 1 out of the way, I can move on to phase 2. Phase 1 was largely about literal operators, ie those defined in a learn rule: OP KET => SUPERPOSITION. But so far I have only hinted that there is also a large collection of function operators, operators that do some processing, eg, mentioned so far: pick-elt, normalize, algebra, and a couple of others.
