ref #38

New API

This PR introduces global_state attribute macro. It replaces GlobalStateand GlobalStatePlugin derive macro.

fn main() {
    App::new()
        .add_plugin(DioxusPlugin::<GlobalState, (), ()>::new(Root))
        .add_plugin(GlobalStatePlugin)
        .add_startup_system(update_todo_list)
        .run();
}

#[global_state]
struct GlobalState {
    todo_list: Vec<UiTodo>,
    // more state if you like...
}

fn update_todo_list(
    mut events: EventReader<UpdateTodoList>,
    mut global_state: EventWriter<GlobalState>,

) {
    for e in events.iter() {
        let todo_list = vec![UiTodo::new()];
        
        // ↓ global_state macro automagically turns GlobalState struct into enum
        global_state.send(GlobalState::TodoList(todo_list));
    }
}
