Add routing

[cvetanov]

Hi,

I really like your idea to make a starter project which incorporates cra and redux. Another really important feature that almost every react + redux app has is probably routing.
Do you think we can add routing in the starter project as well? If so, I can make a PR to support this.

Regards,
Goce

@cvetanov Sure thing. The idea behind those cra-* repos is to have this starters with some tiny tweaks and additional libraries. I was feeling bored of doing the same initial configuration for every project I started
