Construct the scaled Oregonator Mass-Action dynamics in a well-stirred, homogeneous system.

What is often referred to as the “Oregonator” problem is a simplified model of the chemical dynamics of the oscillatory Belousov-Zhabotinsky reaction and due to Fields and Noyes (1974). It is a three-dimensional, stiff initial value problem,

\[\dot u(t) = f(u(t))\]

and a common test problem for numerical solvers for stiff differential equations.
