/**
 * @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
