> The Java API should support setting the parents of a span after the span is created.  This is necessary since some spans may get more parents after they start.  For example, if we have a write-ahead log that we start flushing when a certain number of log entries has accumulated, we may also flush log entries that are created after the flush begins.
> To support this case, the Java API should support setting the parents on a span.  As long as the parents are set before the span is closed, the new parents will show up in the JSON we emit.
