    Thanks for spotting that sentence Billie, will fix tonight.  It's good to
    throw in the rest of the Zipkin configuration as well (I was using the
    default localhost and port).

> Developers who want to go beyond Accumulo's default tracing are too much on their own
to figure out how to use Accumulo's tracing features.  I had to dive deep into source code
to figure out how to understand the trace table format and add a ZipkinSpanReceiver.  I'd
like to share what I found so that other developers do not have to to the same.
