 * Created by: Jonas Rapp https://jonasr.app/
 * Get full solution: https://jonasr.app/2017/09/canary/
 *
 * Writes everything from an IExecutionContext to the Plugin Trace Log.
 *
 * Simple sample call:
 *    tracingservice.TraceContext(context);
 *    
 * Advance sample call:
 *    tracingservice.TraceContext(context, 
 *        includeparentcontext, 
 *        includeattributetypes, 
 *        convertqueries, 
 *        expandcollections,
 *        includestage30,
 *        service);
 *
 *               Enjoy responsibly.

I've made a minor change at https://gist.github.com/MarkMpn/71fb85fd438e44c9f643595a2a1f86a1 - the workflowcontext isn't used and needs me to bring in an extra dependency on my plugin to compile it.

So true, thanks @MarkMpn!
