Radio control instead of checkboxs for layer control

[joaopalotti]

Hi all,

First of all, thanks for this wonderful library.

I am planning to visualize different data slices on top of the same map.
For example, let's say that for the US Unemployment example (https://python-visualization.github.io/folium/docs-v0.6.0/quickstart.html#Choropleth-maps) I have information of unemployment by gender and education.

How can I create an exclusive group control like was done by this plugin (https://github.com/ismyrnow/leaflet-groupedlayercontrol) here using a radio control instead of a checkbox?

Every layer that has the option overlay=True/False can be set to a radio button and cycle the layers available. However, what you want is to group those layers with that plugin and this is not possible without the plugin ;-p

That functionality is a nice candidate for an external plugin but I don't believe it belongs in the core folium. (Happy to be convinced otherwise with a nice PR!)

This was added in #1592, which will be available in the 0.14.0 release.
