The codes accepts 2 arrays as input, and matches each point in the first array to the closest one in the second array.
Accepted format is decimal degrees (positive or negative) in tuples which are separated by commas in a list.
i.e. [(37.7749, -122.4194), (40.6500, -73.9499), (34.0585,-118.2426), (41.8818, -87.6278)]
