Doing some small testing and I did the follwing:

some_marker = folium.Marker(location=[45.5215, -122.6261], popup='test')

I would get this error: AttributeError: 'str' object has no attribute 'get_name'. If I change that to popup=folium.Popup('test') it works fine. Is that intended?

Main reason I'm asking is because it seems somewhat tedious having to call that to assign a string to the popup.
