Base member routes

I have added the base routes for Members
A few things of note:-
 1.  The actual logic for the routes has its own file i.e `route.get('/api/member',getMembers)` resides in `/api/members/getMembers.js`.
The reasons for this are that 
     1. We can unit test each route
     2. Logic is independent of express.
 2.  Since the Models are available everywhere, they moved to `lib/models`

@nic, i'll change the individual issue status when I add each test. :+1:
