add hits to visits

Add hits to visits to really know how many pages renders have your app

I'ts necesary cause when many people use the same IP (ex: hotel) you only get 1 visit for all on the given interval, with this you can have the visits (ip based) and hits (all)

Thanks, @juliangarcess For the PR.

Could you add a presenter for the hits key, something like:

$post->visits->first()->present()->hits

Besides, if you update the README.md would be much appreciated.

Thanks!
