nodejs: groups and per operation permissions

[remyla]

operation based permissions

In Php, we have a permissions.php file which associates groups of users to allowed web service operation (crud operations and others).

• we have 4 default user classes: admin, editor, user, guest
• the users are assigned to a group using a class key under their node
• please see permissions.php and http_service.php files for the current working php version

This issue is partially processed:

the first point is done "user authentication scheme"
(see https://github.com/remyla/damas-core/wiki/Authentication and API https://github.com/remyla/damas-core/wiki/API#Authentication)

i make an issue about the first point and close it (#97)
i edit this issue in order to focus on the second point

[remyla]

• the group based permissions is now up and running in production
• a class key on nodes contains the group name (default declared names are admin, editor, user, guest)
• the permissions for each opetation are written in server-nodejs/routes/permissions.js
