Script Summary: Adds a button to the Waze map editor for selecting all segments in a roundabout
After installation, whenever you select a segment in a roundabout, a "Select roundabout" button will appear in the segment edit panel (below the "Select entire street" button in WME, or where this button would be in WME beta when a non-roundabout segment is selected). Clicking this button will then automatically select the remaining segments of the roundabout.
Note: the button will only appear if the roundabout segment has been selected on its own, or as the first segment in a multi-segment selection. After clicking the button, ONLY the roundabout segments will remain selected.
