Using PersistenceTypes

When creating a DatabaseSettings object and/or creating an instance of a DataContext, one of the persistence types below are required.

- PersistenceTypes.Cookie // uses window.cookieStore to persist data.
- PersistenceTypes.LocalStorage // uses window.localStorage to persist data.
- PersistenceTypes.SessionStorage // uses window.sessionStorage to persist data.
