Visualization enhancement: base-map switch and map zoom-in limitation

[jinningwang]

Issue
When using AGVis, the zoom-in seems to be limited somewhere, as shown in the Figure below:

Desire Feature
First, improve zoom-in limitation.
Can we made some change to alleviate this limitation so AGVis is capable of distribution system visualization? For example, a microgrid on UTK Campus size as attached in the case file. UTCampus.xlsx

Second, is it possible to add option to switch base-map? Maybe street-map?

I apologize for the late reply. It is possible leaflet has been set to have a max zoom, which can be overridden with a single value change, otherwise, this is a limiting factor with the leafletjs library. I will look into this.
