Add legend to leaflet map

[ghost]

Hello, is it possible to add legend to the map? I'd like to legend colors by groups.
Very thanks.

There isn't currently a feature for this but we would really like to add it for a future release.

Would certainly help a lot with choropleth style

@jread-usgs @smach @caspase @pssguy We have added a function addLegend() to this package. Please test it and let us know if you have any comments.

Thanks very much for this.

I want to use it in shiny with the user being able to change the number of bins via a numericInput.

However, the existing legend is not removed

A Work In Progress

In early tests it is working for me as expected, thank you.

@smach Try clicking the link. After the map appears, change the groups to 4. The first legend remains on the map
