double Input::dist

This is the distance that the robot has to go to get to the target. However, if useDistToGoal is set to false, this will return the distance the robot needs to go to be perpendicular to the target.

Example

class DoNothingController : public SpeedController {
public:
    void init() override {
        cout << "I'm doing nothing!" << endl;
    }
    followToRet followTo(Input& input) override {
        //Kinda a bad p controller
        double dist = input.dist;
        return { {dist, forwardVel::pct}, {0, angularVel::pctDiff} };
    }
};
