Move summary to callback result/onCompleted, add examples
- #summarize() lived on the ResultStream from run - which was unhelpful, since the summary is not available until the result is consumed. This instead makes a summary available as an argument to `onCompleted` and as a field on the result object we get when we ask for a full result - Add examples file for the manual.
