Mapping All Colleges

Let's keep layering up and add for-profit colleges to our leaflet map that is stored in the m3 object.

After you print() the m3 map with public, private, and for-profit colleges as their own layers, then try removing all three layers and adding them back to the map in a different order.

The different college sectors are added back to the map as layers in the order you specify (i.e., the last sector that you select will be on top).

The color palette pal and the m3 map with public and private colleges have been loaded for you.
