<%  // Page Description:
    //
    // This page will display the messages of a specified thread. For
    // simplicity's sake all messages in the thread will be displayed in flat
    // mode - that is, all messages will appear under each other without any
    // indentation:
    //
    //  Root Message
    //  [body]
    //     |- Reply 1
    //        [body]
    //     |- Reply 2
    //        [body]
    //     |- Reply 3 (is a reply to "Reply 1")
    //        [body]
    //     |- Reply 4 (is a reply to "Reply 3")
    //        [body]
    //
    // This mode is used because it's easy to illustrate in a skin like this,
    // it's a familiar UI for many forum users and it's easy to paginate (more
    // on this below).
    //
    // It is possible to write a thread page that shows all of the messages
    // in nested order:
    //
    //  Root Message
    //  [body]
    //     |- Reply 1
    //        [body]
    //       |- Reply 3
    //          [body]
    //         |- Reply 4
    //         [body]
    //     |- Reply 2
    //        [body]
    //
    // It's also possible to show just one message per page and make the replies
    // all links to their respective message:
    //
    //  Root Message
    //  [body]
    //     |- Reply 1 [link]
    //         |- Reply 3 [link]
    //             |- Reply 4 [link]
    //     |- Reply 2 [link]
