 *
 * This simple decorator class allows for the delayed construction of the
 * linear solver until the last possible moment when the linear solver is
 * needed.  This class creates LinearOpWithSolveBase objects of type
 * DelayedLinearOpWithSolve.  The class object DelayedLinearOpWithSolve
 * actually implements the delayed linear solver construction.
