*-----------------------------------------------------------------
* @author:iiley (iiley@hotmail.com)
* http://www.robochina.org
* Smoke:use MicroWave to do pattern analyzer and random movement
*--------------------version 0.5 2003.1.5--------------
* 0.5:Can only fire 3 power because MicroWave,so may west much power.(codesize 737)
*--------------------version 0.55 2003.1.5--------------
* 0.55:improved movement a little.(codesize 749)
*--------------------version 0.60 2003.1.8--------------
* 0.60:changed a movement.it does better.(codesize 748)
*--------------------version 0.70 2003.1.25-------------
* 0.70:changed a movement similar to the new verion of Cigaret. (codesize 742)
*--------------------version 0.80 2003.2.3-------------
* 0.80:Squeezed much(MicroWave squeezed too) so added some in aim. (codesize 749)
*--------------------version 0.82 2003.2.5-------------
* 0.82:Squeezed again,added a judge to aim prediction points only in battle feild.
* and can set one color now(but have not set).(codesize 740)
*--------------------version 0.91 2003.7.12-------------
* 0.91:Squeezed again,tweaked movement as experience from Spark.(codesize 742)
*--------------------version 0.95 2003.9.12-------------
* 0.95:Squeezed again,can fire different power bullet and can fight in different battle fileds now.(codesize 748)
*--------------------version 0.96 2004.10.24-------------
* 0.96:Squeezed again,then add a trick to HOT bot, tweaked a little.(codesize 748)
*-------------------------------------------------------
* future:Squeeze so that i can do more and get my whole colors back.
