Oregonator Chemical reaction modelling Oscillator

Oregonator.ar( reset=0, rate=0.01, epsilon=1.0, mu=1.0, q=1.0, initx=0,inity=0,initz=0, mul, add)

Euler ODE solver implementation of the Oregonator equations (http://www.scholarpedia.org/article/Oregonator).

x' = epsilon* (q*y - x*y + x*(1-x) )

y' = mu* (-q*y -x*y +z)

z' = x-y

All inputs can have .kr rate UGens plugged in.

The Oregonator can blow up, treat with caution.

reset- If > 0.0, restart with new initial conditions sampled from initx, inity, initz

rate- update rate for a sample step

epsilon- equation constant

mu- equation constant

q- equation constant

initx- reset value for x

inity- reset value for y

initz- reset value for z

//hits fixed points too quickly
