An ansync stack trace is an object whose purpose is to describe the call sequence and stack frame details that led to the error.

Unlike a normal walkback, the stack frame details are stored internally and there are some adjustments to the stack frames being reported on so the user does not get noise from the frames in the stack trace processing itself.

The debugPrinting capability of a stack trace is not made available since this object may end up in the printed out stack trace as an argument, as it hurts the ability to easily read the stack traces.

To print the stack trace, use EsAsyncStackTrace>>asString

  Answer the contents of the stack trace as a string.
