<p>Backbone connector for a CouchDB backend.</p>
<p>Usage:</p>
<p>var backend = new recline.Backend.CouchDB();
var dataset = new recline.Model.Dataset({
db<em>url: '/couchdb/mydb',
view</em>url: '/couchdb/mydb/<em>design/design1/</em>views/view1',
query<em>options: {
'key': 'some</em>document_key'

});

<p>Alternatively:
var dataset = new recline.Model.Dataset({ ... }, 'couchdb');
dataset.fetch();
var results = dataset.query(query_obj);</p>
<p>Additionally, the Dataset instance may define three methods:
function record<em>update (record, document) { ... }
function record</em>delete (record, document) { ... }
function record<em>create (record, document) { ... }
Where <code>record</code> is the JSON representation of the Record/Document instance
and <code>document</code> is the JSON document stored in couchdb.
When _all</em>docs view is used (default), a record is the same as a document
so these methods need not be defined.
They are most useful when using a custom view that performs a map-reduce
operation on each document to yield a record. Hence, when the record is
created, updated or deleted, an inverse operation must be performed on the original
document.</p>
