This is example repo to reproduce the issue where redux devtools time travel isn't working when using the redux-batched-subscribe store enhancer -> issue 261

1. npm install
2. npm start
3. open the browser at localhost:3000
4. open time travel pane in redux devtools
5. enter some values in the input field
6. try to time travel - the UI isn't changing.
7. go to index.jsx, put line 38 in comment, step 5 works as expected.
