* @shell_view_type: #GType for the corresponding #EShellView subclass.
* @start: Method for notifying the backend to begin loading
* data and running background tasks. This is called
* just before the first instantiation of the
* corresponding #EShellView subclass. It allows the
* backend to delay initialization steps that consume
* significant resources until they are actually needed.
* @migrate: Method for notifying the backend to migrate data and
* settings from the given version. Returns %TRUE if the
* migration was successful or if no action was necessary.
* Returns %FALSE and sets a #GError if the migration
* failed.
*
* #EShellBackendClass contains a number of important settings for subclasses.
