This file contains the generic thinking states for the characters.

Different types of movement or behaviour will be represented by
a seperate thinking function, which may or may not pass control
over to a new behaviour function.

If control is passed onto a new function, the string name of the
current function is returned, mostly for debugging purposes.

!!! NOTE: control must not be passed to a new AI func from outside of
this file. A new AI func must only be called from within another AI func.

This gives us the ability to keep all code related to sections of AI
self-contained, so adding new features to the AI will be less likely to
step on other areas of AI.
