Revise scenario class

[uvchik]

The scenario class was quite big due to historical reasons. Furthermore only part of the class was dumped using the dump method.

1. Use the dump method for the scenario class and not only for the results
2. Clean the scenario class and remove attributes
3. Add a simple compute() method.
