Description

Add the ability to use map view function to filter changes instead of duplicating the
effort in writing a filter function that does the same, which is
apparently done a lot.

Each time a value could be emitted, a change is returned. The url is :

http://127.0.0.1:5984/testdb/_changes?filter=_view&view=dname/viewname

On other advantage is that I can also use this in an external indexer.

Branch is available on my github repo :
