* @short Job that fetches all items of a collection recursive.

* This job takes a collection as argument and returns a list of
* all items that are part of the passed collection and its child
* collections. The items to fetch can be filtered by mime types and
* the parts of the items that shall be fetched can
* be specified via an ItemFetchScope.
*
* Example:
*
* @code
*
* // Assume the following Akonadi storage tree structure:
* //
* // Root Collection
* // |
* // +- Contacts
* // | |
* // | +- Private
* // | |
* // | `- Business
* // |
* // `- Events
* //
* // Collection 'Contacts' has the ID 15, then the following code
* // returns all contact items from 'Contacts', 'Private' and 'Business'.
*
* const Akonadi::Collection contactsCollection( 15 );
* const QStringList mimeTypes = QStringList() << KABC::Addressee::mimeType();
*
* Akonadi::RecursiveItemFetchJob *job = new Akonadi::RecursiveItemFetchJob( contactsCollection, mimeTypes );
* job->fetchScope().fetchFullPayload();
* connect( job, SIGNAL( result( KJob* ) ), this, SLOT( fetchResult( KJob* ) ) );
*
* job->start();
*
* ...
*
* MyClass::fetchResult( KJob *job )
* {
* Akonadi::RecursiveItemFetchJob *fetchJob = qobject_cast<Akonadi::RecursiveItemFetchJob*>( job );
* const Akonadi::Item::List items = fetchJob->items();
* // do something with the items
* }
