/**
 * A default implementation of the node visitor interface. The class introduces
 * several 'summary' methods, that can be overridden to change the behavior of
 * several related visit methods at once. An example is the
 * {@code visitValueLiteral} method, that is called for every
 * {@link ValueLiteralNode}.
 *
 * <p>
 *
 * This is useful to implement a visitor that performs the same operation (e.g.,
 * nothing) for most {@link Node}s and only has special behavior for a few.
 *
 * @author Stefan Heule
 *
 * @param <R>
 *            Return type of the visitor.
 * @param <P>
 *            Parameter type of the visitor.
