Detailed Description

KRoleNames exposes runtime-invokable methods to map from roles to role names and vice-versa. It can be used to retrieve data from a model in an imperative fashion when enum with roles is not available at runtime (i.e. not exported via Q_ENUM macro) but role names are known; or just to maintain consistency with view delegates (which use role names as properties).
