+ * Breadcrumb NavXT - uninstall script
+ *
+ * uninstall script based on WordPress Uninstall Plugin API
+ * 
+ * 
+ * Because bcn_admin->uninstall() does not work with WPMU, 
+ * an uninstaller class has been written, that encapsulates 
+ * the uninstall logic and calls bcn_admin->uninstall() 
+ * when applicable.
+ * 
+ * @see http://codex.wordpress.org/Migrating_Plugins_and_Themes_to_2.7#Uninstall_Plugin_API
+ * @see http://trac.mu.wordpress.org/ticket/967
+ *
+ * this uninstall.php file was executed multiple times because 
+ * breadcrumb navxt (until 3.3) constsisted of two plugins:
+ *
+ *	1.) breadcrumb_navxt_class.php / Core
+ *  2.) breadcrumb_navxt_admin.php / Adminstration Interface
