Source code for VertiLeach V 0.3.3, released under the RoboWiki Public Code Licence (RWPCL).

There are a couple of things that might be interesting with this code:
# It's from a top-10 class bot in RoboRumble@Home (and top-2 class in the MiniBots class)
# It uses a simple GuessFactorTargeting gun
# Rather few lines of code. Even if it has some improvements to ask for in terms of clarity, it isn't as obfuscated as some minibot code out there.
