Add TSV formatted output in transcript, using integer start/end times in milliseconds. (#228)
* Add CSV format output in transcript, containing lines of characters formatted like: <startTime-in-integer-milliseconds>, <endTime-in-integer-milliseconds>, <transcript-including-commas>
* for easier reading by spreadsheets importing CSV, the third
column of the CSV file is delimited by quotes, and any quote
characters that might be in the transcript (which would interfere with
parsing the third column as a string) are converted to "''".
* fix syntax error
* docstring edit
