 A redux Thunk implementation for async action dispatch. 
+Thunk implement must implement the `Thunk` interface, which only has one dispatch method.
+A more friendly way to create a thunk is with the `createThunk` function.  Both are illustrated below:
 
 ```
     val store = createStore(::reducer, applymiddleware(thunk))

-        dispatch(FetchingFooAction)

-            if (result.isSuccessful()) {
-                dispatch(FetchFooSuccess(result.payload)
-            } else {
-                dispatch(FetchFooFailure(result.message)
