The supplied example ("Lentille") does not seem to work.
The directories are only partially filled, there is no Lentille.html file generated. Installation was made via 'python setup.py install').
Reported version (using 'p2n --version' is 2.1.0, but I suspect it is 3.0.0.dev5 (obtained via 'git clone -b develop https://github.com/Patent2net/P2N.git').
