/// Helpers for asynchronously executing a base::[Once|Repeating]Closure (bound

///   void MyFunc(int arg) { /* do something with |arg| on the UI thread */ }
///   // Post a task that will execute MyFunc on the UI thread and pass an |arg|
///   // value of 5.
///   CefPostTask(TID_UI, base::BindOnce(&MyFunc, 5));

///   // Define a class.
