tracing: Tracing infrastructure Add a new feature "tracing" that enables tracing functionality via the "tracer" crate (sadly features and crates cannot share the same name.) Setup: tracer::start() The main functionality is a tracer::trace_scope()! macro that will add trace points for the duration of the scope. Tracing events are per thread. Finish: tracer::end() this will write the trace file (pretty printed JSON) to a file in the current directory.
