Tracing demonstration

Augmenting Dapper-like spans with low-level tracing captured by DTrace. The Span contex is passed into DTrace at the start of the Span using a USDT probe (opentracing*:jaeger:span:start) and cleared at the end of the span (opentracing*:jaeger:span:finish).

Within the duration of the Span DTrace scripts can correlate tracing with the Span through a predicate that checks for the presence of the Span Context stored in the thread local variables.
