erp5_web: reuse the web section logic

parent dda798db
"""
This script is part of ERP5 Web
ERP5 Web is a business template of ERP5 which provides a way
to create web sites which can display selected
ERP5 contents through multiple custom web layouts.
The default implementation searches for
documents which are in the user language if any
and which reference is equal to the name parameter.
Other implementations are possible: ex. display the last
version in the closest language rather than
the latest version in the user language.
NOTE:
- the portal parameter was introduced to
fix acquisition issues within the _aq_dynamic
lookup from WebSection class.
