Hello:),

1)
module Greeting
  def say_hello
    puts "Hello, my name is #{self.name}"
  end
end

class Foo
  attr_accessor :name
  include Greeting

  def initialize(name)
    @name = name
  end

end

2)
class Bar
  extend Greeting
end

3)

class Example

  attr_accessor :name

end

4) Client waits until request finishes even if client doesn't download 
any data. Implement a background service to generate large files, 
implement user notification service to notify user after file is 
generated and ready to use.
