Boosting Practice

This map is for practicing the mineral boosting trick I introduced. See the following thread if you do not know this technique:
http://www.teamliquid.net/forum/viewmessage.php?topic_id=152345

The map features:
1) Tracks your % of successful mineral boosts in the top left
2) Timer in the top right
3) Type "-r" to reset the map and "-v" to end the map
4) Missed boosts causes workers to glow red and show "Miss!"

There are still some bugs, but it is good enough for practicing this trick.
