/**
 * This service allows to generate and manage all the visible views by the
 *  current connected user, as well as to generate orgcharts PDF
 *  corresponding to a view. <br>
 * The views are defined in the views.xml file.<br>
 * The generation of a view is done in two steps:<br>
 *
 *    1.  Call to the ViewGenerator service that plays the motor role of
 *        TreeNode generation.<br>
 *        These TreeNodes include the DefaultMutableTreeNode that will allow
 *        to generate the graphic party of the views.<br>
 *        The service ViewGenerator has also the role to call the view plugin
 *        configured in the views.xml file.<br>
 *
 *    2.  Call to the graphic generator.
