Foreign Key Constraints are disabled

[ezcoding]

When trying to set a foreign key for a column an assertion fails with the message:
assertion failed: foreign key constraints are disabled

Are they disabled by default? If yes, how can I enable them?
Thank you for this lib. It is awesome btw ;)

Please see https://www.sqlite.org/foreignkeys.html#fk_enable for more information. (Note that you'll have to enable it per database connection at this time, so if you call Database() multiple times in your app, you'll need to execute the given statement, as well.)
