- Removed the cartopy dependency. While some users were able to install it, overall it proved to be difficult to reliably build across multiple operating systems. Instead, I use the pyshp pure python library to read in the Esri shapefile files to make the map. Currently, only the mercator projection is supported. However, in the future, I plan to add other projections such as orthographic.
- Renamed asilib.create_cartopy_map() to asilib.make_map()
