Example preset for how to use the datafield_latlongmap field with the database list view.
Map-enabled version of the Database activity latlong field.
Needs plugins local_map for map API, and datafield_latlongmap for a latlong field that supports maps.
This is being built against Moodle 2.6+, but should work for at least 2.5.
If you're familiar with Git and can set up a test Moodle, the easiest way to try is to clone it from GitHub: https://github.com/Dave-B/moodle/tree/master_maps
This is a plugin version to help people unfamiliar with Git to try it; I'd like to get it included in core (MDL-42522).
