示例1: remove
/**
* Remove the persistent instance of an object permanently.
*
* Deletes the persistent object isntance stored in the database when
* called, including any dependent objects defined by composite foreign key
* relationships.
*
* @todo Implement some way to reassign ownership of related composite
* objects when remove is called, perhaps by passing another object
* instance as an optional parameter, or creating a separate method.
*
* @param array $ancestors Keeps track of classes which have already been
* removed to prevent loop with circular references.
* @return boolean Returns true on success, false on failure.
