Work division strategy (3 people)

1. Definition of top-level code interface:
2. Tristan: Series class (series.hh)
3. Théo: define DumperSeries class (dumper.hh)

2. Definition and implementation of Series subclasses:
3. Tristan: ComputePi class (pi.hh and pi.cc)
4. Théo: ComputeArithmetic class (arithmetic.hh and arithmetic.cc)
5. Théo: modification of main to execute series (main.cc)

3. Definition and implementation of DumperSeries subclasses:
4. Tristan: PrintSeries class (print.hh and print.cc)
5. Théo: WriteSeries class (write.hh and write.cc)

4. Re-definition of printing methods in DumperSeries:
5. Tristan: modify DumperSeries and PrintSeries classes

5. Evluation of complexity:
6. Flavio: modify Series, ComputePi and ComputeArithmetic classes to optimize computation

6. "Bonus":
7. Flavio: Implementation of exhaustive, robust testing and options in main file
