The saga::replica class implements the saga::attributes interface.
A logical file represents merely an entry in a name space which has (a) an associated set of registered (physical) replicas of that file, and (b) an associated set of meta data describing that logical file. Both sets can be empty. To access the content of a logical file, a saga::file needs to be created with one of the registered replica locations.
