rsc3-arf - rsc3 alternate rate flow

Unit generator constructors evaluate to a
procedure (rate -> ugen).

The root of the graph is at audio rate.  Inputs
run at the rate of the unit generator they connect
to.  Branches introduce lower rate sub-graphs
using the kr and ir functions.

Names of rsc3-arf unit generators are equal to
those of the ordinary rsc3 unit generators, one or
the other must be renamed.
