Helps turn polygon markers on Kanka maps into lines to represent paths.
Adds a button to the polygon marker editor in Kanka maps that manipulates coordinates in the text field in order to turn them into a single line. For example, you can click any three points on the map and activate the Helper to end up with a continuous line instead of an enclosed triangle. This can be used to represent paths or to indicate boundaries without covering a whole region, or potentially to create some simple drawings.
