sync.rb

# **sync.rb** is a Sinatra-based webapp that acts as a sync connector between 
# [Zendesk](http://www.zendesk.com) and [Trello](http://trello.com)
# The whole app would benefit from some caching and a resque worker queue, since it's
# getting a little slow.
#
# This is the Sinatra routes file that defines the API of the webapp
