/**
 * A trace is a series of spans (often RPC calls) which form a latency tree.
 * 
 * Spans are usually created by instrumentation in RPC clients or servers, but
 * can also represent in-process activity. Annotations in spans are similar to
 * log statements, and are sometimes created directly by application developers
 * to indicate events of interest, such as a cache miss.
 * 
 * The root span is where parent_id = Nil; it usually has the longest duration
 * in the trace.
 * 
 * Span identifiers are packed into i64s, but should be treated opaquely.
 * String encoding is fixed-width lower-hex, to avoid signed interpretation.
