/**
 * The interface for an object which determines what the "next" view to show is,
 * and then causes the ViewHandler to set that view as the current one.
 * 
 * The JSF specification defines the behaviour of a default implementation of
 * this interface. An alternate implementation can be used by configuring the
 * appropriate element in the application's faces-config.xml file.
 * 
 * See the javadoc for this class in the
 * JSF Specification
 * for more details.
