// Modified from fork origin:
// Adapted for use in https://github.com/dave-null/piratenmandate-frontend

// Usage:
//   var someButton = new L.Control.Button(options).addTo(map);
// This calls OnAdd(). See the code for what options are required
// The third parameter passed to L.DomEvent.addListener is the 'this' context
// to use in the callback (second parameter).
