We've added a path mapper to support simple mapping between path objects used in the storage layer and the underlying file system. The target of this is to ensure that paths are only calculated in a single place and their format is separated from the data that makes up the path components. This commit only includes spec implementation to support layer reads. Further specs will come along with their implementations.
