Description

ExportTool doesn't properly handle anonymous child docs or nested docs.   It also confuses the JSONL format with the JSON format.  

I'd like to have the JSON Lines format output as .jsonl, which is the standard, and have the JSON format to be a .json, which is the same output as if you wanted to post a Solr doc as a JSON to upload the data...    This will let us round trip the data.
