Detailed Description

This class provides an API to building, displaying and manipulating World maps and countries in BRIDGES.

In the current implementation, we can draw a World map with all country boundaries, or specify a set of countries and display the country boundaries.

Functions are provided to access each country county and color its boundary, its interior using stroke and fill color functions. This lets us build map based applications where the fill color can be used to represent different data attributes, such as population counts, election statistics or any attribute at the country level. We stop at the country level as each country has its own subdivisions, such as discticts, states, regions, counties, etc.

The default constructor allows to get a basic map fo the entire world and supports no styling.

See the Maps tutorials for examples of the usage of the World Map API at https://bridgesuncc.github.io/tutorials/WorldMap.html
