-    Wails Bridge (c) 2019-present Lea Anthony
-
-    This library creates a bridge between your application
-    and the frontend, allowing you to develop your app using 
-    standard tooling (browser extensions, live reload, etc). 
-
-    Usage:
-    ```
-    import Bridge from "./wailsbridge";
-    Bridge.Start(startApp);
-    ```
-
-    The given callback (startApp in the example) will be called
-    when the bridge has successfully initialised. It passes the
-    window.wails object back, in case it is not accessible directly.
