Switch
======

**Energy.Base.Switch** is a simple boolean switch with an `OnChange` event. It can be implicitly converted from a `bool` and explicitly converted back to a `bool`.

Example
-------

```csharp
Energy.Base.Switch light = new Energy.Base.Switch(false);

light.OnChange += (sender, e) =>
{
    Console.WriteLine("Light state changed");
};

light.On();     // fires OnChange
light.Value = false;

bool state = (bool)light;
```
