[glob2-devel] Echo AI system commit

[Bradley Arsenault]

I have commit my first version of the Echo AI system, along with my
test ai, ReachToInfinity. If you want to test it, there is one
important thing you should note, its that the Echo may run slowly
without compiler optmizations. Compiler optmizations can be done with
./configure CXXFLAGS="-O3". The optmizations are enabled by default on
release builds, but not for general purpose cvs.

A couple of benifits of Echo:
- It scales well, you can put 8 of them on a map, and it will barely
use more cpu than if you put only one of them on a map.

- For people interested in making an AI, Echo hides allot of the
little annoyyances when dealing with glob2

- Echo (although not yet) is self contained, which means that I
could, in one weekend, port it to a scripting language, allowing for
scripting AI's.

- Echo could easily be interfaced with maps, and, because of its
low-barrior design towoards making an AI, it would be easy to make
map-specific AI's for the campaigns, and more importantly, the
tutorial.
