Example how to use Firebase Queries

[ilionic]

Based on Docs:
'With the release of GeoFire 3.1.0, this library now uses the new query functionality found in Firebase 2.0.0.'
In particular I am interested in limitToLast query found in Firebase with expected usage:

geoFireRef.limitToLast(2).on("key_entered", function(key, location, distance) { ...

But it throws an error TypeError: geoFireRef.limitToLast is not a function
Is it possible to use Firebase queries in GeoFire?

That sentence in the docs refers to how GeoFire functions "under the hood," so to speak. GeoFire internally uses Firebase queries. It still doesn't have an API to limit to a certain number of results, although you can pretty easily get this functionality with little to no performance loss. Check out issues #59 for some ways to do that.
