Efficient finite difference derivatives for algebraic modelling systems

TL;DR: A procedure is described which determines Jacobian incidence structure and the constant/nonconstant nature of each Jacobian element via examination of the text of function expression strings via examination for algebraic modelling systems and other systems with interpreted functions which require evaluation of first derivatives.
