-/**
- * HTTP Digest Authentication handler
- *
- * Use this class for easy http digest authentication.
- * Instructions:
- *
- *  1. Create the object
- *  2. Call the setRealm() method with the realm you plan to use
- *  3. Call the init method function.
- *  4. Call the getUserName() function. This function may return false if no
- *     authentication information was supplied. Based on the username you
- *     should check your internal database for either the associated password,
- *     or the so-called A1 hash of the digest.
- *  5. Call either validatePassword() or validateA1(). This will return true
- *     or false.
- *  6. To make sure an authentication prompt is displayed, call the
- *     requireLogin() method.
