Pillow is a combined router and rereducer for CouchDB.

Dependencies (Both of these are included in this git repository):
- webmachine
- ibrowse from jungerl

Needless to say, it also depends indirectly on couchdb. There is no direct dependencies, but what use is a router
or rereducer for CouchDB without CouchDB. 

Roadmap:
The current goal is to add resharding to Pillow. 
X  Automatic generation of resharding validate functions *Done*
X  Automatic resharding using validate functions *Done*
X  CouchDB style config files *Done*
X  Resharding controlled through the config file. The [routing] section is the
   original routing config. [resharding] is the intended routing config. Call
   pillow_routing_table:reshard() to start replicating to the new nodes. Observe
   that the replication completed before executing pillow_routing_table:flip() to
   start using the new nodes. flip also updates the config. At this point, the old    servers may be torn down. *Done*
X  Monitoring UI that will show stats and general health of Pillow *Done*
X  End-to-end resharding through a single call. Pillow will wait until replication is
   complete before flipping to the new servers. Tearing down the old ones will still
   be manual. *Done*
X  control script
X  Daemonize Pillow
X  Control script handling resharding
2. Time to move from deployment script to configure/make install
