Detailed Description

Wraps one setting for Model creation.

A BackendSetting consists of an option type and an option value. The option type can either be a predefined value from Soprano::BackendOption or a user defined string value that depends on the Backend implementation. In the latter case option has to be set to Soprano::BackendOptionUser.
