Shape file overlay

This feature is added in v18.06 for beta testing. We recommend our users to utilize it with a caution and keep us posted about the experiences with it. A single shapefile can be overlayed over the baseline map in a geography type question. This shapefile must be placed into the folder TheWorldBank/Shared/ShapefileCache/ and must contain all three mandatory shapefile components (*.shp, *.shx, and *.dbf) accompanied with the *.prj. Consult the ESRI tools and documentation for the structure of the shapefile and the role of these components.
