Build Pipeline

* Uses ESM Modules
* When using @web/dev-server, Chrome has better error messages than Safari when loading modules fails

What the workflow client is doing
o on start a Client_impl instance is created to receive either feedback from
  server, or when there is none, 

new Client_impl // strip the _impl, it's a CORBA convention but inside the app's code we don't care
    constructor(orb: ORB, server?: inf.Server)
       server.setClient(this)
  
    async logonScreen(lifetime: number, disclaimer: string, inRemember: boolean, errorMessage: string)

    async homeScreen(cookie: string, avatar: string, email: string, fullname: string)
        board = server.getProject(1).getBoard(1)
        model = board.getModel()
        model.board = board
        const listener = new BoardListener_impl(orb, boardmodel)
        board.addListener(boardListener)
        bind("board", model)
      
    async offline()
        let model = new LocalLayerModel()
        let layer = new LocalLayer()
        model.layers.push(new LocalLayer())
        bind("board", model)

flow when working with a server:
                      |                          |
  FigureEditor -> BoardModel -> Server -> BoardListener_impl -> FigureEditor.updateView()
                      |                          |
      client                   server                          client
