	/**
	* SmartTemplate Class
	*
	* 'Compiles' HTML-Templates to PHP Code
	*
	*
	* Usage Example I:
	*
	* $page = new SmartTemplate( "template.html" );
	* $page->assign( 'TITLE',  'TemplateDemo - Userlist' );
	* $page->assign( 'user',   DB_read_all( 'select * from ris_user' ) );
	* $page->output();
	*
	* Usage Example II:
	*
	* $data = array(
	*             'TITLE' => 'TemplateDemo - Userlist',
	*             'user'  => DB_read_all( 'select * from ris_user' )
	*         );
	* $page = new SmartTemplate( "template.html" );
	* $page->output( $data );
