/********************************************************************************
    Debug Variables - show debugging results in another window using javascript.
    
    The original saved into a file then displayed it in a window 
        and was written by Alter Gr <alt-hide@address.com>.
    
    The new version by John Lim <hide@address.com>
        1. writes directly to the debug window without using an intermediate file
        2. supports all types, including objects, floats and booleans
        3. cleans up strings with < correctly using htmlspecialchars()
        4. added msg()
        5. added recursion check in v2()
    
    Tested with IE 5.5 and Netscape 4.77 and 6.
    
    usage:    
            $D = new LensDebug();
            $D->v($var1,"var1"); // display a variable and its type
            $D->msg('Show a text message');
    
            second parameter is optional
