Using the maps Caucasus-ethnic_en.svg and Lezgin_map, write a file in GeoJSON (or similar) format for use by pairmapper's languages-as-areas plugin. The file should contain specifications for the area(s) the following languages are spoken in: Lezgi, Azeri (Azerbaycan), Azeri (Iran), Ingush. There should be a certain level of detail (e.g., don't just make a shape matching Kazakhstan for Kazakh) and accuracy (i.e., don't just put a square over Kazakhstan and call it the area for Kazakh).
