Adding Approutes using react-router;

#9 can be closed now as the folder currently has been refactored, @ivanoats for extension of features of orcamap v1 in react-based, we would need to extend few components as per Q1-Q2 roadmap.
Further routes can be added using the current react-router.

This adds React Router - but why? What significant code does it add that needs routes? Also, does it conflict with any other previous outstanding PRs? #26 ?

[parthsarthiprasad]

@ivanoats I might have to rebase and resolve merge conflict if #26 is merged prior to this. I was thinking of adding further routes following suggestion from previous PR of #9 only.
If we only have a single map component then we won't require any usage of routes but
was in consideration of further addition of pages in future ?
What are your suggestions?
