* This class provides storage for the tokens that is set in "remember me"
* cookies. This way no password secrets will be stored in the cookies on
* the client machine, and thus the security is improved.
*
* This depends only on doctrine in order to get a database connection
* and to do the conversion of the datetime column.
*
* In order to use this class, you need the following table in your database:
* CREATE TABLE `rememberme_token` (
* `series` char(88) UNIQUE PRIMARY KEY NOT NULL,
* `value` char(88) NOT NULL,
* `lastUsed` datetime NOT NULL,
* `class` varchar(100) NOT NULL,
* `username` varchar(200) NOT NULL
* );
