An extension to easily create or update GUI.
Call the method Show of the BABYLON.GuiEditor class:
BABYLON.GuiEditor.Show({hostElement: document.getElementById("host")});
This method will retrieve dynamically the library babylon.guiEditor.js, download it and add
it to the html page.
If you don't have access to internet, the gui editor should be imported manually in your HTML page :
<script src="babylon.guiEditor.js" />
