/**
 * Get an object which will perform manipulation of dummy content.
 *
 * Return any object which is a subclass of RealisticDummyContentBase, which

 *
 * @param object $entity
 *   The object for a given type, for example this can be a user object
 *   or a node object.
 * @param string $type
 *   The entity type of the information to change, for example 'user' or 'node'.
 * @param array $filter
 *   (Default is array()).
 *   If set, only certain fields will be considered when manipulating
 *   the object. This can be useful, for example for users, because
 *   two separate manipulations need to be performed, depending on whether
 *   hook_user_insert() or hook_user_presave(). Both hooks need to modify
 *   only certain properties and fields, but taken together the entire
 *   object can be manipulated.
 *   The filter is an associative array which can contain no key (all
 *   fields and properties should be manipulated), the include key (fields
 *   included are the only ones to be manipulated, or the exclude key (all
 *   fields except those included are the ones to be manipulated).
 *
 *   realistic_dummy_content_api_user_insert() defines the array
 *   ('exclude' => array(picture)) whereas
 *   realistic_dummy_content_api_user_presave() defines the array
 *   ('include' => array(picture)). Therefore taken together these two
 *   hooks manipulate the entire user object, but in two phases.
 *
 *   This allows hook implementations to return a different class based on
 *   the type of filter.
 *
 * @return array
 *   Array of objects which are a subclass of RealisticDummyContentBase.
