[CM] lisp loop iteration in cm

[Juan I Reyes]

Thanks a lot Rick!

As my understanding now, the 'process' macro behaves very much like the
'loop' macro in CL. This is great and very sophisticated!

Certain (a,b) duplets make the attractor periodic and stable in short
periods. These are very good to map rhythms but they will need to be
constrained to CM's durations. Therefore if I find Henon values which
are too periodic I will constrain them and map them to rhythm.
