Card suggestion based on location

[TheLastProject]

It would be interesting to store a combination of:

1. Timestamp
2. GPS coordinates
3. Card ID

And whenever a card is opened, save a new entry to this.

Then, we could every 5 minutes or so check the current GPS coordinates and suggest a card that matches nearby coordinates.

For example: You go to the grocery store, and open your grocery store card. Catima stores the GPS location where you opened the card. So, the next time you go to the grocery store, Catima can create an Android notification telling you that it thinks you're at the grocery store and allowing you to open the grocery store card with a single tap.

This is more of an experiment and will need a lot of tweaking to figure out how to make it helpful but not creepy (even though we will of course not send any data online, we don't want to scare any user). And of course this should be fully optional.
