    Welcome to the "core" PySimpleGUIWeb code....
    
    This special port of the PySimpleGUI SDK to the browser is made possible by the magic of Remi 
    
    https://github.com/dddomodossola/remi 
    
    To be clear, PySimpleGUI would not be able to run in a web browser without this important GUI Framework
    It may not be as widely known at tkinter or Qt, but it should be.  Just as those are the best of the desktop
    GUI frameworks, Remi is THE framework for doing Web Page GUIs in Python.  Nothing else like it exists.
