Instead of having people treat latitude and longitude as separate things, just add a 'location_t' data structure that contains both. Almost all cases want to always act on them together. This is really just prep-work for adding a few more locations that we track: I want to add a entry/exit location to each dive (independent of the dive site) because of how the Garmin Descent gives us the information (and hopefully, some day, other dive computers too).
