/**
* @short Base class for jobs that need to run a sequence of sub-jobs in a transaction.
*
* As soon as the first subjob is added, the transaction is started.
* As soon as the last subjob has successfully finished, the transaction is committed.
* If any subjob fails, the transaction is rolled back.
*
* Alternatively, a TransactionSequence object can be used as a parent object
* for a set of jobs to achieve the same behaviour without subclassing.
*
* Example:
*
* @code
*
* // Delete a couple of items inside a transaction
* Akonadi::TransactionSequence *transaction = new Akonadi::TransactionSequence;
* connect( transaction, SIGNAL( result( KJob* ) ), SLOT( transactionFinished( KJob* ) ) );
*
* const Akonadi::Item::List items = ...
*
* foreach ( const Akonadi::Item &item, items ) {
* new Akonadi::ItemDeleteJob( item, transaction );
* }
*
* ...
*
* MyClass::transactionFinished( KJob *job )
* {
* if ( job->error() )
* qDebug() << "Error occurred";
* else
* qDebug() << "Items deleted successfully";
* }
*
* @endcode
