Behavior
--------
If you construct a Database explicitly, the Database inherits any options from
the :php:`MongoDB\\Driver\\Manager <class.mongodb-driver-manager>` object. If
you select the Database from a :phpclass:`Client <MongoDB\\Client>` object, the
Database inherits its options from that object.
