Loading/Waiting modal

Idea created by Faye Business Systems Group Developers on Sep 14, 2017

    The SDK wide loading and error alerts are not fully visible in a lot of cases.  We need some UI element that can cover pop up in the middle of the screen.  This is useful when we are communicating with servers and waiting for the responses.  That way we can stop the interaction with certain parts of the UI.  It will also be a lot easier for the user to see what's going on.
