public ManyToOneHelper::addTable($join = NULL, $alias = NULL)
Add a table to the query.
This is an advanced concept; not only does it add a new instance of the table, but it follows the relationship path all the way down to the relationship link point and adds *that* as a new relationship and then adds the table to the relationship, if necessary.
