Add TSV formatted output in transcript, using integer start/end times in milliseconds. (#228)

Browse Source 
* 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

Write a transcript to a file in TSV (tab-separated values) format containing lines like:

Using integer milliseconds as start and end times means there's no chance of interference from
an environment setting a language encoding that causes the decimal in a floating point number
