 * @JTourBusStop 0.0, Interaction, createPartControl - Entry Point of the
 *               plugin:
 * 
 * This is the setup-entry-point for this plugin. The Eclipse Platform calls
 * this method when it initializes this view.
 * 
 * The following connections between the classes get established here: - A
 * new treeviewer is created for showing the routes later on. - The
 * associated ContentProvider is created and connected to the viewer. - A
 * label provider is created and connected also. - The view-part subscribes
 * to selection listener here (so when the user selects something new we can
 * change our view)
