A Better Mongoid Sinatra configuration implementation. Using settings hash for db options sucks!
View mongoid3_sinatra_config.rb
# This is a modification of the blogpost on how to use Mongoid and Sinatra.
# Here is the original blogpost http://www.garrensmith.com/2010/09/11/Mongoid-sinatra.html
# The modification lets you use Mongoid 3.0 with the new Moped driver
# The new Moped driver uses the Sessions component to define the MongoDB connection rather
# than the Mongo::Connection.new that is used in the case of the default Ruby driver.
# Moped::Session.new vs Mongo::Connection.new
# Mongoid.load!(yaml_config.yml) is used to build the config hash. Alternatively, the hash can
# be built manually by using Mongoid.config {|config| ...} syntax. The config.sessions hash
