nested scala classes -> jerkson parse/generate -> store/retrieve in cassandra.io

sample

class Address(street: String, street2: String, city: String, state: String, zip: String) {}

class User(email: String, shippingAddress: Address, billingAddress: Address) {}

def storeUser(user: User) = {
 val userjson = jerkson.generate(user)
 // put this userjson in cassandra
 WS.url(URL + "/" + java.util.UUID.randomUUID()).post(userjson)
}

def retrieveUser(id: String): User = {
 val response = WS.url(URL + "/" + id).get()
 jerkson.parse[User](response.body)
}
