* Adds an object to the instance pool.

* to the cache in order to ensure that the same objects are always returned by find*()
* and findPk*() calls.
*
* @param \WpTermRelationships $obj A \WpTermRelationships object.
* @param string $key (optional) key to use for instance map (for performance boost if key was already calculated externally).
