 We currently do not have a validation system in place.  It would be useful to have a neb-fsck program that could do the following things:
- 1) Scan the instance table, and confirm that the files exist on disk.
- 1) Confirm that the md5sum matches for all instances of a given storage object.
- 1) Scan the nebulous directory trees and identify files that do not have a matching entry in the instance table.  These files could be reinserted, as the full disk path describes the ins_id and the ext_id for a given file.  It could be reassociated with the storage_object (if it exists), or simply deleted.

 In addition, all nebulous tasks that create a file or copy a file should validate that the files agree before the function completes successfully.  Not doing this can introduce errors if we silently replicate a broken copy of the file.
