[tryton] edit report template on the client side

[Vincent Mora]

Hi all,

I'm developing a couple of modules for tryton (should be release 
open-source) 

I'd like reports to be modified on the client side.

On http://doc.tryton.org/3.0/trytond/doc/topics/reports/ I found an empty 
section "Creating a simple report template for a model from client".

Can someone give me pointers to achieve that (I'm willing to fill the empty 
section afterward).

Thanks,

V.
