/**
 * TDbUserManager class
 *
 * TDbUserManager manages user accounts that are stored in a database.
 * TDbUserManager is mainly designed to be used together with {@link TAuthManager}
 * which manages how users are authenticated and authorized in a Prado application.
 *
 * To use TDbUserManager together with TAuthManager, configure them in
 * the application configuration like following:
 * <code>
 * <module id="db"
 *     class="Prado\Data\TDataSourceConfig" ..../>
 * <module id="users"
 *     class="Prado\Security\TDbUserManager"
 *     UserClass="Path\To\MyUserClass"
 *     ConnectionID="db" />
 * <module id="auth"
 *     class="Prado\Security\TAuthManager"
 *     UserManager="users" LoginPage="Path\To\LoginPage" />
 * </code>
 *
 * In the above, {@link setUserClass UserClass} specifies what class will be used
 * to create user instance. The class must extend from {@link TDbUser}.
 * {@link setConnectionID ConnectionID} refers to the ID of a {@link TDataSourceConfig} module
 * which specifies how to establish database connection to retrieve user information.
