> Develop a generic LazyList class which implements iterator interface and can be used with the CloudFiles and S3 driver.
> CloudFiles and S3 API limits the maximum number of objects which can be returned in a single response which means that on subsequent request you need to provider extra parameters to get the next set of results (marker, prefix, etc.).
> This class should transparently encapsulate this paging process and list_container_objects() in CloudFiles and S3 method should return an instance of this class.
> The class should also be "lazy" which means that new set of results should only be requested when the current result set is exhausted.
