"""Example configuration file

This file illustrates how to define options and simulation parameter ranges.
It also defines the traversal order of the simulation space. As the file
extension suggests, configuration is pure python code, allowing complex
setups. Use at your own risk.

To use this example, run
   python3 study.py config_example

Otherwise copy it and modify as needed. The default traversal order defined
in the nested loop of nextShape() is good for most cases, but customizable
if needed.
