Ordered algebraic Equation Solver
You can select either of two demonstration
example models. The first of those is a simple noniterative
calculation, which just uses the tool as a calculator.
The second is an example of solving a pair of equations iteratively.
The `Solve' button produces the results of the iterative solution in a separate window; scroll down to see the final answer.
The `Show Model Data' button will list the complete current model
in a single window.
