    // Name: Logging IP's
    // Description:This is basically an IP-l
    //     ogger, which keeps a record of if a pers
    //     on with that ip has been there before.
    This is great for counters which will prevent refresh-increasing the count. Just place the counter-events witin the correct function. The Welcome-part and not the Welcome back.
    // By: Klaus Andersen
    //
    // Returns:The main function returns tru
    //     e and false, depending on if the curren 
    //     ip of the browser is in the file.
    //
    // Assumes:Basic php knowledge. But clip
    //     and paste will work just as good.
    //
    // Side Effects:There might be bugs, I h
    //     avent tested it enough, if there is a fl
    //     aw please post a reply.
