Notice:
The definition of button is not exactly "button form" in front end, it may be threejs's object or pic, we may change it latter.
Now I add a button, user can click this button to return to solar system.
The solar system support click the planet to switch to planet scene.
As a user, I want to change scene between planets and solar system, so that I can look around.
Definition of done: Add "switch button" function to demo.html, to let user can switch between different scene with click the "button".
