grab geo data on location creation

[tsujigiri]

When a Location gets created, we want to pull corresponding geo data and store it with the location.

We should do that in the background (e.g. with Delayed::Job) for the user not having to wait for the geo data.

Related: Latitude and longitude should be unalterable. When an instrument is being moved, a new location should be created, otherwise all related samples get moved, too.

changing an instruments location != changing a locations coordinates

changing an instruments location == adding a new location and changing the setting of the instrument to the new location

on the other hand: changing coordinates of a location is fine in case of solving an error

agreed

How about asking the user if this is a relocation or correction when he changes the coordinates? Additionally we could put a notice next to the coordinate fields describing what happens when he changes them.

Possible sources:

• http://www.geonames.org/
• https://code.google.com/apis/maps/documentation/geocoding/ (limited to 2500 requests per day, "geocoding results without displaying them on a map is prohibited")

I will start this now, using geonames.org and resque as job queue

As it is working now, should we close it? Or is there anything else?

Should be good for now - closing :)
