    Before using Python threads, or libraries using threads, must apply
    GObject.threads_init().This is needed because GTK+ isn't thread safe.Only
    one thread,the main thread, is allowed to call GTK+ code at all times.
    This function isn't provided by gobject but initializes thread support
    in PyGObject (it was called gobject.threads_init() in pygtk).
    Contrary to the naming actually it is gi.threads_init().

    GObject.idle_add() takes the function and arguments that will get passed to
    the function and asks the main loop to schedule its execution in the main
    thread.

    Instantiate models and views , then pass it to the main_controller.
