Updated TODO + renamed babel -> router

TODO

 Bugs :
-    When no peer is avalaible without the --no-boot option, it crash
+    When no peer is avalaible without the --no-boot option, it crash => see below
 
 To be done :
-    Replace comments at the beginning of functions with docstrings
+    Replace comments at the beginning of functions with docstrings & give all fn docstrings
     Do a clean-up in the import
     Remove the parameters to choose the number of clients
 
 To be discuss:
     Remove the --no-boot option since we know when no node is avalaible
+       \=> the no-boot option is only useful when the server knows no peer,
+           irl it should never happen, no-boot is a debug option
 
     The organisation of the code
         vifibnet.py         Just contain the main loop and the init
-        openpvn.py          To launch openvpn processes
-        utils.py            Small functions to do some usefull job, also contains the config
-        db.py               Function to access the DB (merge with utils ?)
+        plib.py             To launch server/client/routing processes
+        utils.py            Small functions to do some usefull job
+        db.py               Function to manage peers
         tunnelmanager.py    To choose wich connection delete/keep/...
         upnpigd.py          To open a port and find the external IP
 
     How we choose which protocol we use :
-        IMO, we should use UDP. I've read many times than TCP other TCP can be catastrophic in terme of performance 
+        IMO, we should use UDP. I've read many times than TCP other TCP can be catastrophic in terme of performance
         Every time a packet is lost, it is resend 2 times, one for each TCP tunnel
         And many GW allow UDP port forwarding (for bittorent, Xbox, ...) but not TCP port forwarding
