/**
* @short Job that moves items/collection to trash.
*
* This job marks the given entites as trash and moves them to a given trash collection, if available.
*
* Priorities of trash collections are the following:
* 1. keepTrashInCollection()
* 2. setTrashCollection()
* 3. configured collection in TrashSettings
* 4. keep in collection if nothing is configured
*
* If the item is already marked as trash, it will be deleted instead
* only if deleteIfInTrash() is set.
* The entity is marked as trash with the EntityDeletedAttribute.
*
* The restore collection in the EntityDeletedAttribute is set the following way:
* -If entites are not moved to trash -> no restore collection
* -If collection is deleted -> also subentites get collection.parentCollection as restore collection
* -If multiple items are deleted -> all items get their parentCollection as restore collection
*
* Example:
*
* @code
*
* const Akonadi::Item::List items = ...
*
* TrashJob *job = new TrashJob( items );
* connect( job, SIGNAL(result(KJob*)), this, SLOT(deletionResult(KJob*)) );
*
* @endcode
