physical and virtual returns a list with named elements

Details

ff objects have physical and virtual attributes, which have different copying semantics: physical attributes are shared between copies of ff objects while virtual attributes might differ between copies. as.ram will retain some physical and virtual atrributes in the ram clone, such that as.ff can restore an ff object with the same attributes.
