    Used by pyramid_cubiweb to store the session datas.

    It is a partial copy of the yet-to-integrate patch of cubicweb that
    provides cubicweb sessions persistency.

    While the same structure will be used by pyramid_cubicweb persistent
    sessions and Cubicweb persistent sessions, the two concepts are slightly
    different and will NOT co-exist in a single application.
