Initial code to retrieve a spot from firebase.  Fix bug of no reviews.  Need to reformat display for intial data load. Also, add spot should not refresh but redirect to the new spot page.
Refactored addSpot so correctly formats crowdfactor.day.
Redirect to spot page after adding a spot.
Add cf status none to _calcualteStatus and no watches return time for _getStatus.
Fix divide by 0 in cf_score calculation with new 0 entry for no data.
