Plotting centroid coordinates

Because we can't plot whole bounding boxes, we summarize the bounding box location into a single point called a centroid. Plotting these on a Basemap map is straightforward. Once we calculate the centroids, we separate the longitudes and latitudes, then pass to the .scatter() method.

The Basemap object m has been created for you. The dataset tweets_sotu and function calculateCentroid() have also been loaded.

Calculate the centroids and store in centroids.
Set the argument zorder in fillcontinents such that the continents appear behind the points.
Plot the points. Remember to set the latlon argument to the correct value.
