Description

FSDirectory's path resolution currently uses a mixture of string & byte[][] conversions, back to string, back to byte[][] for INodesInPath. Internally all path component resolution should be byte[][]-based as the precursor to instantiating an INodesInPath w/o the last 2 unnecessary conversions.
