> FSShell should support creating symlinks.  This would allow users to create symlinks
from the shell without having to write a Java program.
> One thing that makes this complicated is that FSShell currently uses FileSystem internally,
and symlinks are currently only supported by the FileContext API.  So either FSShell would
have to be ported to FileContext, or symlinks would have to be added to FileSystem.  Or perhaps
we could open a FileContext only when symlinks were necessary, but that seems messy.
