Allow design docs to specify custom sort orders for composite keys
------------------------------------------------------------------

                 Key: COUCHDB-144
                 URL: https://issues.apache.org/jira/browse/COUCHDB-144
             Project: CouchDB
          Issue Type: Bug
          Components: Database Core
            Reporter: Nick Johnson


Currently, there is no way to construct an index with different sort orders on different subkeys.
For example, you might want to have a view of users sorted by city ascending, then age descending.
With some data types this is easy enough to fudge by negating the values (eg, integers, floats,
bools), but with strings this is currently practically impossible to achieve. I'm implementing
a CouchDB interface for App Engine apps, and this issue is a blocker, preventing me from finishing
it.

>From a conversation with damienkatz in IRC:
<damienkatz> I was going to say it seems fine to add key array collation info the design
docs
<damienkatz> something like {key_array_collation:["asc", "desc", "desc"], ...}
<damienkatz> create a new bug for it.
