Title: Add drawcounties method

Here is the first go at adding functionality for drawing counties on a map. It reads in a UScounties shapefile dataset, which has been added to the data directory.

One note is that the resolution of the default draw methods (coastlines, countries, states, etc) can be changed. Using the shapefile provides only one resolution. Thus when drawing counties on a low or intermediate map resolution, differences between counties/states, counties/countries, counties/coastlines can be found when zoomed in.
