/**
 * An object of the ezcWorkflowNodeEnd class represents an end node of a workflow.
 *
 * A workflow must have at least one end node. The execution of the workflow ends
 * when an end node is reached.
 * Creating an object of the ezcWorkflow class automatically creates a default end node for the new
 * workflow. It can be accessed through the getEndNode() method.
 *
 * Incoming nodes: 1
 * Outgoing nodes: 0
 *
 * Example:
 * <code>
 * <?php
 * $workflow = new ezcWorkflow( 'Test' );
 * // build up your workflow here... result in $node
 * $node = ...
 * $workflow->startNode->addOutNode( ... some other node here ... );
 * $node->addOutNode( $workflow->endNode );
 * ?>
 * </code>
