You must use macros for map/reduce view functions, because CouchDB
must know every change that you make to those functions, otherwise it
won't know when to update the index linked to that view. Using require
would make it possible to change the behaviour of a map function
without changing it's source code, by changing a require'd function.
Therefore we need to resort to the more primitive mechanism of

Fortunately CouchApp solves that problem for us.
