[Karl Lieberherr]

This is of great interest to the entire class: Ahmed is proposing a
key/value pairs approach
as an alternative.

How would you answer his questions?

The second approach is to define the configuration object in the
scg.cd. However, make it generic. For example, a configuration object
can have a list of key/value pairs such as:

In your opinion what would be the pros and cons of both approaches.
Which one would you choose? and What is you rationale for doing so?
