SPAppIFrame class
The SPAppIFrame control is used by SharePoint App developers to iframe remote pages into thier SharePoint pages. The SPAppIFrame provides several useful features for this scenario: 1) The src attribute of the SPAppIFrame can start with the ~remoteAppUrl token which will get resolved into the url to the Azure VM that the SPApp was installed into. 2) SPAppIframe supports postmessage communications that lets the iframed content send a resize message to the parent page to resize the iframe.
