Setup

Add loveseat package and setup.py with install_requires.
Basic Client

Implement the basics for supporting the Couch HTTP interface with
primitives for Server, Database and Document objects. Define Servers as
being a collection of Databases and Databases as being a collection of
Documents. Define simple Resource class as a lightweight wrapper around
the requests library filling in a few defaults for common headers Couch
expects to see during requests.
Mapper Interface

Add mapper module which includes a base mapper that all models should
inherit from and a handful of useful property types.

Add get_server and get_database functions to the client for retrieving
global server and database objects after initialize has been called.

Update Server interface to include a uuids property that stores a cached
list of uuids from the server for use when generating document ids.
