     Manage commnunication between browser tabs.
     this js lib can perform several actions on browser tabs like :
+        - (*new) search and kill zombies tabs (enable onload by default)
         - append/rewrite/synchro node on all (other) tabs or a specific tab (and possibly on specific frame context) eventually with callback.
         - reload all tabs or a specific tab with specified url or tab 's current url
         - perform your custom actions on all tabs or specific tab
