  * Adds an object to the instance pool.

  * Propel keeps cached copies of objects in an instance pool when they are retrieved
  * from the database.  In some cases -- especially when you override doSelect*()
  * methods in your stub classes -- you may need to explicitly add objects
  * to the cache in order to ensure that the same objects are always returned by doSelect*()
  * and retrieveByPK*() calls.
  *
  * @param Translation $obj A Translation object.
  * @param      string $key (optional) key to use for instance map (for performance boost if key was already calculated externally).
