need a demo without kv language

[s0h3ck]

Let's say we take the example in the README.md and we write it in Python (without kv language).

Two issues:

• contextmenu stays when you click outside the contextmenu (for example, on the button)
  What I should be expected: it would be hidden when you click something that is not part of the menu.
• on touch system doesn't stop at the contextmenu (the button gets triggered as well).

        layout.canvas.remove(button.canvas)
        layout.canvas.insert(0,button.canvas)

        self.add_widget(layout)

class TestApp(App):
    def build(self):
        return Test()

if __name__ == "__main__":
    app = TestApp()
    app.run()

Maybe we could take inspiration from NavigationDrawer to improve this garden repository. It could involve some changes.

We will appreciate any suggestions.

Thanks.
