Checking permissions in Rails

What we will use:

CanCan - Authorization Gem for Ruby on Rails (https://github.com/ryanb/cancan)
Response module (will be covered later)

Let's just start with an example

Let's suppose that you have a method do_something, which could be preformed only by user who's matching permissions view_payment_info, if options[:some_key] isn't

Organizing `lib` directory with static services

`base_service.rb`

    module Core end

    module Core::BaseService
 extend self

	random_emoji() {
	emojis=(📚 🚀 🐍 🌎 🎉 🎸 🌈 💻 🌿 🍀 🌝 🍊)
	selectedexpression=${emojis[$RANDOM % ${#emojis[@]} ]}
	echo $selectedexpression
	}

	export PS1="$(random_emoji) $ "

	# install convoy

	wget https://github.com/rancher/convoy/releases/download/v0.5.2/convoy.tar.gz
	tar xvzf convoy.tar.gz
	sudo cp convoy/convoy convoy/convoy-pdata_tools /usr/local/bin/
	sudo mkdir -p /etc/docker/plugins/
	sudo bash -c 'echo "unix:///var/run/convoy/convoy.sock" > /etc/docker/plugins/convoy.spec'

	# download and execute preparation script
