  Requirements:
  1/ Manually copy the DeprecatedHeaders folder from the SDK's {install-dir}/FacebookSDK/FacebookSDK.framework/Versions/Current into your project's Supporting Files directory
  2/ Instantiate an instance of the Facebook class.  This class implements the dialog:andParams:andDelegate method.  Example:
         self.facebook = [[Facebook alloc] initWithAppId:@"{app-id}" andDelegate:self];

  Note: several dialogs from this list: https://developers.facebook.com/docs/reference/dialogs/ are unsupported on iOS / Android touch devices.  The following don't work:
    1/ add page tab
    2/ (add) friends
