Alexander Neumann 5cdcc99eba Use array instead of hash for backend.ID ... Since backend.ID is always a slice of constant length, use an array instead of a slice. Mostly, arrays behave as slices, except that an array cannot be nil, so use `*backend.ID` insteaf of `backend.ID` in places where the absence of an ID is possible (e.g. for the Subtree of a Node, which may not present when the node is a file node). This change allows to directly use backend.ID as the the key for a map, so that arbitrary data structures (e.g. a Set implemented as a map[backend.ID]struct{}) can easily be formed.		2015-07-25 18:01:57 +02:00
