let cloudantURL = NSURL(string:"https://username.cloudant.com")!
let client = CouchDBClient(url:cloudantURL, username:"username", password:"password")
let dbName = "database"

// Create a document
let create = PutDocumentOperation(id: "doc1", body: ["hello":"world"], databaseName: dbName) {(response, httpInfo, error) in
    if let error = error {
        print("Encountered an error while creating a document. Error:\(error)")
    } else {
        print("Created document \(response?["id"]) with revision id \(response?["rev"])")
    }
}
client.add(operation:create)

// create an attachment
let attachment = "This is my awesome essay attachment for my document"
