Interactive functionality

[Thommynator]

Goal

Implement some interactive functionality to the project, e.g.

• show only best car, hide others
• change (increase/decrease/toggle) mutation rate
• add trace for each car, which visualizes the driven path (requires trace feature Car Traces / Driven Path / Trajectory #4)
• use neural network of best car for all other cars
• save neural network of current best car (requires save feature Save Neural Network as JSON #7)
• load neural network (requires load feature Load Neural Network from JSON #8)

Current State

Nothing in place.

Hints / Notes

Some kind of Key Listener and/or UI would be good (buttons).

Started to work on some of the features in this commit.

• use neural network of best car for all other cars
• save neural network of current best car (requires save feature Save Neural Network as JSON #7)
• load neural network (requires load feature Load Neural Network from JSON #8)

These menu options are now working...

Added new features.

• Switch between: "Show all cars" vs. "Show only best car".
• Toggle mutation rate
• Change racetrack by mouse drag. add & remove
