/**
* A visitor that decorates another {@link EvaluationVisitor}, to intercept
* invocations of the <code>visitXxx(...)</code> methods. By default, every
* visitation is simply delegated to the decorated visitor. Subclasses may
* extend these delegations with any additional behaviour that is required,
* even replacing calls to the delegate where necessary.
* <p>
* This class works together with the {@link AbstractEvaluationVisitor} to
* ensure that recursive <code>visitXxx()</code> calls are correctly intercepted
* by me (and not just implemented within the decorated visitor). Moreover,
* this works with decorators nested to any depth.
