    // counter.php - implements a simple Cou
    //     nter
    //
    // Author: Claus Radloff
    //
    // Description:
    // The counter in this file can count mu
    //     ltiple counters. Therefore
    // every counter gets it┤s own identifie
    //     r.
    // The Fore- and Backgroundcolor and the
    //     number of digits are
    // defined, but can be overwritten. Fore
    //     - and Backgroundcolor may
    // be transparent as well.
    // The Parameters are passed in the URL.
    //
    // Some Examples:
    // simple counter:
    //<img src="counter.php?Identifier=Te
    //     st">
    //
    // Counter with red background
    //<img src="counter.php?Identifier=Te
    //     st&BGColor=255+0+0">
    // or:
    //<img src="counter.php?Identifier=Te
    //     st&BGColor=red">
    //
    // Counter with red background, green fo
    //     reground and 4 digits
    //<img src="counter.php?Identifier=Te
    //     st&BGColor=255+0+0&FGColor=0+255+0&Lengt
    //     h=4">
    // or:
    //<img src="counter.php?Identifier=Te
    //     st&BGColor=red&FGColor=green&Length=4"&g
    //     t;
    //
    // Counter with transparent background a
    //     nd red foreground
    //<img src="counter.php?Identifier=Te
    //     st&BGColor=transparent&FGColor=red">
