Answers and Retrieval
   - In the simplest case, a new problem is presented.
 
   - The system searches the casebase for the most similar case.
 
   - It retrieves that along with the answer.
 
   - It then trots out the answer as the answer to the new problem.
 
   - It is possible to retrieve multiple close cases.  The system
       could then present all of those to the user, or do something
       with all the answers.
 
   - The system could also  adapt the
       answer.
 
   - However the obvious question is what makes one case similar to 
       another?
