    This looks great.  Thanks, Dylan!  I have two suggestions.  One is about the sentence,
"Span entries record full span information, whereas index and start time entries provide indexing
into span information useful for quickly finding spans by type or start time."  Actually both
the span and start time entries have the full span information, while only the index entries
provide indexing.
    
    The other suggestion is to mention other configuration properties that would need to be
set for the zipkin span receiver in accumulo-site.xml and in the client configuration, such
as:
    ```
    <property>
      <name>trace.span.receiver.zipkin.collector-hostname</name>
      <value>localhost</value>
    </property>
    <property>
      <name>trace.span.receiver.zipkin.collector-port</name>
      <value>9410</value>
    </property>
    ```

> 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.
