Date:   Fri Oct 21 14:54:59 2011 +0200

    Implement basic transaction processing.

    In case if state is "Submitted" start transaction.

    In case of other acceptable states (like initial, to be done, etc) mark such
    state and just continue.

    Any other state generates error, according to idea: only what is excpeted,
    allows to be silent.

    _requestIfNeeded decortor is not needed.

    Do real analysis out of initial transaction.

    As logs are stored in ZODB, transaction have to be committed. But it is
    obvious, that sent data shall result in failure, but in such case transaction
    would be rolled back, and no log would be stored.

    So commit activity, which will handle the analysis.
