Hi Johan:

here is the set of cds we have tried:

/proj/adaptive/www/demeter-method/cd-design/strats/
v1-final-exam/   
v2-no-graphs/
v3-with-graphs/

Please can you come up with one for the improved notation
we had this morning.

The design of a class dictionary for strategies has 
gone through several phases. 

Some highlights:

0. The original notation is a series-parallel graph notation.

1. View strategies as trees: S = Segment "(" List(S) ")".
v1-final-exam/   

2. View strategies as forests of trees:
v2-no-graphs/
   Strategy :
     TreeStrategy | // contains at most one strategy
     ForestStrategy | // contains several strategies
     StrategyName.

3. Also allow a set of classes or edges to be a strategy.
v3-with-graphs/
   Strategy :
     TreeStrategy | // contains at most one strategy
     ForestStrategy | // contains several strategies
     StrategyName |
     ClassesEdges.
