-----------------------------------------------------------------

The updated specification reflects the semantic change to the permission setting of the automated
created directories. Now it is set to be the disjunction of 0500 and the permission of the
closest existent ancestor.

> I'm working on adding a permissions model to hadoop's DFS. The first step is this change,
which associates user info with files. Following this I'll assoicate permissions info, then
block methods based on that user info, then authorization of the user info. 
> So, right now i've implemented adding user info to files. I'm looking for feedback before
I clean this up and make it offical. 
> I wasn't sure what release, i'm working off trunk.
