Allow setting of field locations as lat/lng coords

[srkirkland]

Until we get a fancy map, allow creation of locations as a passed set of lat/lng coordinates. Probably using KML format will be useful to start since it can be exported from google earth pro: [lng],[lat],[elev][space] [lng],[lat],[elev].

Goal is to get the data associated with the quote and then project so we can see the locations drawn on a simple map, and mostly so we get the db structure correct and working with complex geometry.
