Types of plugs:

• All plugs must define two methods: init and call

• Function plugs:

  Methods declared within module which takes a Plug.Conn and optional options and do some transformation.

• Module Plugs:

  Standalone module which can be used by specifiying a plug command

  plug MyPlug

• Plugs are chainable:

plug :one
plug :two
plug :three


def one(conn,_opts) do
  # transformation
end

def two(conn,_opts) do
  # transformation
end

def three(conn,_opts) do
  # return final data and transformation
end
