> Coprocessor based implementation of per-KV security that extends the existing 
> AccessController and ACL model to cover per cell permissions. More comments 
> on this approach can be found on the parent issue. Stores and consults the 
> additional metadata in a shadow column family managed by the 
> AccessController. Preserves existing user facing semantics. Does not require 
> any changes to core code except, optionally, the security shell commands, for 
> testing and prototyping convenience.
