coalesce stream output in the notebook...

coalesce stream output in the notebook This merges consecutive outputs on one stream into a single output. Essentially, it applies the same merging that we do visually to the content stored in the notebook document. This results in a massive performance improvement in load-time and storage size for notebooks that have many calls to `sys.stdout.flush()`.
