Testing the control-rate functionality.

This is a big milestone.  It looks like it fits about alright.  Next
is to perform some tests.  A time-variable filter would be nice.
Probably best to do this in Pd.

Possible application: low pass, driven by the c/s samples.

EDIT: elements necessary to make testing easier
- Load compiled C code into racket
- Fix ai-stream.rkt OK
- Fix ai-array.rkt based new ai-stream.rkt semantics (sample at t=0) OK
