Maes Nets
   - We've done some planning work with 
       Maes nets, from 
       
	 How To Do The Right Thing or 
       
	 How To Do The Right Thing .
 
   - The idea here is that you have facts, goals, and actions with
       preconditions and results, quite
       like in Strips.
 
   - You have modules which connect these things.
 
   - However, these are connected with connections that
       enable them to spread activation.
 
   - Some modules and goals may be connected because the actions from these
       modules fulfill or partially fulfill the goals.
 
   - Activation spreads throughout the net, with goals set by the user
       and facts set by the environment.
 
   - When a module gets sufficient activation, it fires and causes its
     associated action to be applied.
 
   - This updates the network, and activation continues to spread.
 
   - We've spent some time implementing this in simulated neurons.
