# :title: MapPoint Object Testing Script
# This script runs the MapPoint object through some simple tests
# 
# * Point instantiation
# * Point inspection
# * Instantiated point configuration
# * ToString method test
# * Object conversion to radians
# * Test boolean in_radians method
# * Test distance functions global point set
# * Test distance functions local point set
