Add option to ignore less-accurate readings

[ijanos]

After pressing resume while GPS accuracy was still ~300m the app recorded some outlier points.

It would be nice to have an option to ignore all measurements that are above a certain GPS accuracy threshold.

@merlos Maybe a good way to solve this would be simply to expose locationManager.distanceFilter to user in prefs.

What do you think?

distanceFilteris used to minimize the number of updates. The definition: it is the minimum distance(measured in meters) a device must move horizontally before an update event is generated.

So, if for example, we set a distanceFilter of 50, the app will get a position update when the user moves 50m from current location.

What I was thinking is to expose in preferences a cell with a slider to allow the user to set the minimum accuracy required for a location to be recorded. The slider can have increments of 10m or just a few points, such as: High accuracy (<15m) Good accuracy (<50m) Regular accuracy (<100m) Any accuracy (< oo)
