public function Table::link in Data 8

Link this table to another table. Linking a table to another one is to define how data in these tables should be joined to each other.

There can be more than one link to the left of a table. However, for views integration, only the first join created will be used.

@todo: Get rid of link() language, use setJoin()/removeJoin() instead.
