Major - P3 When using the mongo driver by itself in IRB, creating a client with a URI raises the following error:
2.2.3 :007 > db = Mongo::Client.new(ENV['MONGOLAB_URI']) NameError: uninitialized constant URI from /Users/david/.rvm/gems/ruby-2.2.3/gems/mongo-2.1.2/lib/mongo/uri.rb:339:in `decode' from /Users/david/.rvm/gems/ruby-2.2.3/gems/mongo-2.1.2/lib/mongo/uri.rb:293:in `parse_user!' from /Users/david/.rvm/gems/ruby-2.2.3/gems/mongo-2.1.2/lib/mongo/uri.rb:259:in `parse_creds_hosts!' from /Users/david/.rvm/gems/ruby-2.2.3/gems/mongo-2.1.2/lib/mongo/uri.rb:243:in `setup!' from /Users/david/.rvm/gems/ruby-2.2.3/gems/mongo-2.1.2/lib/mongo/uri.rb:195:in `initialize' from /Users/david/.rvm/gems/ruby-2.2.3/gems/mongo-2.1.2/lib/mongo/client.rb:340:in `new' from /Users/david/.rvm/gems/ruby-2.2.3/gems/mongo-2.1.2/lib/mongo/client.rb:340:in `create_from_uri' from /Users/david/.rvm/gems/ruby-2.2.3/gems/mongo-2.1.2/lib/mongo/client.rb:198:in `initialize'

This issue is resolved by including
require 'net/http'
before any calls to the mongo driver, but if an external package is required in a library, it should require it itself.
