These databases are user-specific and QML-specific. They are stored in the \c Databases subdirectory
of QmlEngine::offlineStoragePath(), currently as SQLite databases.
-The API is based on the HTML5 offline storage SQL draft API. The main difference is that this QML
-API is currently synchronous. You should avoid relying on synchronicity to make your scripts more

-Opens a database identified by the given \c name and \c version.
-If a database with this name and version does not exist, it is created. The \c version should
