[Users] Use of append_branch

[Bogdan-Andrei Iancu]

Hi Doug,

if you call append_branch() with no param, the RURI will be pushed as 
new branch. So, you can try to modify the RURI as you like and then push 
it as branch.

If you need to backup the RURI during the operation, use an AVP to 
backup into it.

regards,
bogdan
