<h2>Detailed Description</h2>
<p>Job that begins a session-global transaction.
</p>
<p>
Sometimes you want to execute a sequence of commands in
an atomic way, so that either all commands or none shall
be executed. The TransactionBeginJob, TransactionCommitJob and
TransactionRollbackJob provide these functionality for the
Akonadi Job classes.
