[Cs5500] SCG Game design

[Karl Lieberherr]

/home/lieber/.www/courses/se-courses/cs5500/sp11/GenericSCG/anush-rashmi/march9

is the directory for the improved, more modular, game definition
approach that Anush and Rashmi
sent based on feedback from Ahmed.

To prepare for the exam, ask questions of the form: how would this
game definition approach
be impacted if we add feature f to the game. Do this in your teams.
