Leaflet Group Support

Yes, groups are currently not supported. A little javascript might be required for turning on/off layers. An easy button could work as well.

I hope you don't mind. I added support for leaflet::addLayersControl(). It does not work exactly like how leaflet does it. I did it in using CSS classes and Javascript. Added group and className to the function parameters. Works for both baseGroups and overlayGroups.

This is my first time to modify a package. For now, I put my example/test code in its own folder. I am not sure if I should put examples in the roxygen blocks or in a separate file. I'll defer to you on that. I'll polish my work before I submit a pull request.

Also, if you want to add a example put it in roxygen documentation at the end of the other code snippets. The examples folder is not included in the package build
