/**
 * 
 * Provides a simple implementation of {@link ConfigurableNavigationHandler}
 * that can be subclassed by developers wishing to provide specialized behavior to an existing
 * {@link ConfigurableNavigationHandler} instance. The default implementation of all methods is to call through to the
 * wrapped {@link ConfigurableNavigationHandler}.
 * 
 *
 * 
 * Usage: extend this class and push the implementation being wrapped to the constructor and use {@link #getWrapped} to
 * access the instance being wrapped.
