Hello World for ContextR

    example do
      class MyApplication
        def greet
          "Hello, World"
        end
      end

      app = MyApplication.new
      assert_equal "Hello, World", app.greet
    end

And what about request coming from down under? Let's introduce Localization.

    example do
      class MyApplication
        in_layer :au do
          def greet
            "G'day, mate"
          end
        end
      end

      app = MyApplication.new

      assert_equal "Hello, World", app.greet

      ContextR::with_layer :au do
        assert_equal "G'day, mate", app.greet
      end
    end

And what if down under changed its habbits? Let's redefine it.

    example do
      class MyApplication
        in_layer :au do
          def greet
            super + " and God Save the Queen"
          end
        end
      end

      app = MyApplication.new

      assert_equal "Hello, World", app.greet

      ContextR::with_layer :au do
        assert_equal "Hello, World and God Save the Queen", app.greet
      end
    end

The key here is, that the method `greet` method in the `:au` layer is redefined
and no new method is added.

    example do
      class MyApplication
        in_layer :au do
          $inner_module_1 = self
        end
      end
      class MyApplication
        in_layer :au do
          $inner_module_2 = self
        end
      end

      assert(($inner_module_1 == $inner_module_2), "Modules should be equal")
    end
