30    @file CountDown.cc
31    @brief Countdown HUD element, counting down from CountDown::counter_ to zero.
32   
33    In use it would like this:
34        @code
35        <OverlayGroup name="spacefightHUD" scale = "1, 1">
36          <CountDown
37              position    = "0.49, 0.05"
38              pickpoint   = "0.0, 0.0"
39              font        = "ShareTechMono"
40              textsize    = 0.06
41              colour      = "1.0, 1.0, 1.0, 1.0"
42              align       = "right"                 
43              counter     = "10.0"
44              speedfactor = "1.0"
45              active      = "false"
46           >
47            <events>
48              <activity>
49                <EventListener event="startcounting" />
50              </activity>
51            </events>
52          </CountDown>
53        </OverlayGroup>
54        @endcode
55        The counter is triggered by an event called "startcounting" and counts from 10 to 0.
