-A localizable text column is visible as two properties:
-The plural-name property (e.g. Pokemon.names) is a language-to-name dictionary:
-  bulbasaur.names['en'] == "Bulbasaur" and bulbasaur.names['de'] == "Bisasam".
-  You can use Pokemon.names['en'] to filter a query.
-The singular-name property returns the name in the default language, English.
-  For example bulbasaur.name == "Bulbasaur"
-  Setting pokedex.db.tables.default_lang changes the default language.
+See `pokedex.db.multilang` for how localizable text columns work.  The session
+classes in that module can be used to change the default language.
