"""This example illustrates the usage of creator, evaluator and generator.
All the steps of airfoil creation & evaluation are detailed here;
however, the generator.py module contains certain presets (default airfoils).
Create an airfoil;
Evaluate an airfoil;
Generate a population of airfoils & optimize.
