er-rectangle, the
      spatial dimension, the solution, if known, and a title for the problem.
      These routines have a standard set of names based on the function index.
      For instance, for function #3, we have the routines:
      <ul>
        <li>
          <b>P03_AB</b> returns bounds for problem 3.
        </li>
        <li>
          <b>P03_F</b> returns the objective function value for problem 3.
        </li>
        <li>
          <b>P03_M</b> returns the spatial dimension for problem 3.
