Using angular dependency injection with react, redux, and redux-thunk
var thunkDispatcherRef = {
dispatch: function () {}
}
/**
* The angular injection middleware allows our redux actions to return functions.
*
* The function will be executed with regular angular dependency injection, allowing
* you to use angular services in Redux actions.
*
* The redux-thunk also operates on actions that return functions. We interact with
* thunk by: 1) Adding a provider for the `dispatch` function used by thunk. 2) Carefully
* checking the arguments, and if a `dispatch` argument exists, passing redux-thunk a
* function that will correctly execute the angular function with the new dispatch funcion.
