/**
* Removes assets from a schema that are not in the default namespace.
*
* Some databases such as MySQL support cross databases joins, but don't
* allow to call DDLs to a database from another connected database.
* Before a schema is serialized into SQL this visitor can cleanup schemas with
* non default namespaces.
*
* This visitor filters all these non-default namespaced tables and sequences
* and removes them from the SChema instance.
