Fixed a few errors with the bundle install, removed an extra column that was already there and updated the readme.
Updated readme with better instructions.
Changed to add a truck_limit to locations, and to enforce that truck limit.
Added support for a location based limit on trucks.  Need to still support multiple vendor ids in the locations.geojson
Fixed time_slot.rb to check future slots.  Not just current slots.
This fixes the problems with food trucks being logged in but not showing up.  We still need to make it so that if a food truck is registered even without a time slot, they show up.
Cleaned up some comments and made start time allowed to equal, but not exceed end time
Removed some debug output from ticket model.
