Remote Control Cleanup

class Outer
{
    public interface IInner {}
    public enum EInner {}
    public class CInner {}
    public struct SInner {}
}

var outer = new Outer();
var inner = new Outer.CInner();

Instructions

Some "other" developers have been working on the remote control car project remote-control-competition. You have been called in to clean up the code.

1. Separate concerns between the car itself and the telemetry system

Refactor the RemoteControlCar class to move to separate out telemetry methods and properties accessed via a Telemetry property.

var car = new RemoteControlCar();
car.Telemetry.Calibrate();
car.Telemetry.SelfTest();
car.Telemetry.ShowSponsor("Walker Industries Inc.");
car.CurrentSponsor
// => "Walker Industries Inc."
car.Telemetry.SetSpeed(100, "cps");
car.GetSpeed()
// => "100 centimeters per second"

2. Prevent other code taking too many dependencies on the Telemetry type

Ensure that the Telemetry instance cannot be created outside the scope of the car.

3. Prevent other code from taking dependencies on the Speed struct

Ensure that the Speed struct cannot be used outside the scope of the RemoteControlCar class.

4. Prevent other code from taking dependencies on the SpeedUnits enum

Ensure that the SpeedUnits enum cannot be used outside the scope of the RemoteControlCar class.
