This issue is related to #52 but is a sub-issue for implementing a W3C trace context propagator in particular. The specification for [W3C Trace Context](https://github.com/w3c/trace-context) also has a [reference implementation](https://github.com/w3c/trace-context/blob/master/test/tracecontext/traceparent.py) which may be used. Additionally, there is an implementation in [opencensus](https://github.com/census-instrumentation/opencensus-python/blob/master/opencensus/trace/propagation/trace_context_http_header_format.py) which can be referenced.
