 *  \brief A default implementation for authentication data in %Wt::%Dbo
 * 
 * This class implements the requirements for use as a data type in
 * Wt::Auth::Dbo::UserDatabase.
 *
 * It is a template class, and needs as parameter the Dbo type which
 * models a user (e.g. name, birth date, ...). Thus, this class only
 * carries the authentication information for that user.
 *
 * It contains collections to two other types:
 *  - authTokens() references a collection of authentication tokens, see
 *    AuthService::setAuthTokensEnabled()
 *  - authIdentities() references a collection of identities, which represent
 *    all the authentication identities this user has (e.g. a login name, but
 *    also an OAuth identity, etc...)
 *
 * To use these classes, you need to map three classes to tables of your
 * choice.
 *
 * \code
 * class User; // your user Dbo type
 * typedef Wt::Auth::Dbo::AuthInfo<User> AuthInfo;
 *
 * session->mapClass<User>("user");
