/**
 * Common DataBase Connexity Table Manager Class
 * This class factorize code for CommonDBChild and CommonDBRelation. Both classes themselves
 * factorize and normalize the behaviour of all Child and Relations.
 * As such, several elements are directly managed by these two classes since 0.84 :
 * - Check:  all can* methods (canCreate, canUpdate, canViewItem, canDeleteItem ...) are
 *           defined.
 * - Update: when we try to update an attached element, we check if we change its parent item(s).
 *           If we change its parent(s), then we check if we can delete the item with previous
 *           parent(s) (cf. "check" before) AND we can create the item with the new parent(s).
 * - Entity: Entity is automatically setted or updated when setting or changing an attached item.
 *           Thus, you don't have any more to worry about entities.
 *            (May be disable using $disableAutoEntityForwarding)
 * - Log:    when we create, update or delete an item, we update its parent(s)'s histories to
 *           notify them of the creation, update or deletion
 * - Flying items : some items can be on the stock. For instance, before beeing plugged inside a
 *                  computer, an Item_DeviceProcessor can be without any parent. It is now possible
 *                  to define such items and transfer them from parent to parent.
 *
 * The aim of the new check is that the rights on a Child or a Relation are driven by the
 * parent(s): you can create, delete or update the item if and only if you can update its parent(s);
 * you can view the item if and only if you can view its parent(s). Beware that it differs from the
 * default behaviour of CommonDBTM: if you don't define canUpdate or canDelete, then it checks
 * canCreate and by default canCreate returns false (thus, if you don't do anything, you don't have
 * any right). A side effect is that if you define specific rights (see NetworkName::canCreate())
 * for your classes you must define all rights (canCreate, canView, canUpdate and canDelete).
 *
 * @warning You have to care of calling CommonDBChild or CommonDBRelation methods if you override
 * their methods (for instance: call parent::prepareInputForAdd($input) if you define
 * prepareInputForAdd). You can find an example with UserEmail::prepareInputForAdd($input).
