Different contexts might require the same expression to be evaluated to different orders of functional differentiation; for example, in setting up a linear system, second-order derivatives are required, but in evaluating a functional only zeroth derivs are required.
An EvaluationContext is used as a key to associate an evaluator and its corresponding set of functional derivatives with a context.
They key consists of three parts: first, an integer identifier indicating the caller, e.g., an assembler or functional evaluator, second, a set indicating which orders of differentiation are required by the top level caller, and third, a region-quadrature combination.
