/**
 * eGW API - framework: virtual base class for all template sets
 *
 * This class creates / renders the eGW framework:
 *  a) html header
 *  b) navbar
 *  c) sidebox menu
 *  d) main application area
 *  e) footer
 * It replaces several methods in the common class and the diverse templates.
 *
 * Existing apps either set $GLOBALS['egw_info']['flags']['noheader'] and call common::egw_header() and
 * (if $GLOBALS['egw_info']['flags']['nonavbar'] is true) parse_navbar() or it's done by the header.inc.php include.
 * The app's hook_sidebox then calls the public function display_sidebox().
 * And the app calls common::egw_footer().
 *
 * This are the authors (and their copyrights) of the original egw_header, egw_footer methods of the common class:
