=begin
    install Sinatra: gem install sinatra
    install Shotgun: gem install shotgun (this auto-reloads sinatra on every http request - which means every time you make a change in your code you don't have to stop then start sinatra)

    To just run your code using Sinatra: ruby name-of-file.rb
    To run your code using Shotgun (which is just Sinatra but with ability to auto-reload when changes are made to files): shotgun name-of-file.rb

    The following examples are run using Shotgun and the URL is: http://127.0.0.1:9393/
