Issue Description

I would like to display the user's location with the standard updating blue dot while using Cluster on a mapview, but I cannot figure out how to do this.
I have tried to figure it out in the example app as a base solution, but checking the User Location box for the map in the storyboard doesn't add it. I have also tried to programmatically add it using:

mapView.showsUserLocation = true

but this doesn't work either (though I may have put it in the wrong place).

I am guessing this is a simple fix that I am just not seeing; any help would be much appreciated!
