> I introduced generic types for FSNamesystem class.
> I tried to keep interfaces in declarations of the member as general as possible
> in order to have flexibility to change types of instances in the future.
> I tried to contain changes within one java file.
> I also replaced Vector types by ArrayList. Vectors are synchronized,
> which we don't need since we already have top level synchronization in FSNamesystem.
