/* Optional helper class for outputting CSV data.  Use like:

	CsvWriter csv("out"); // no .csv suffix

	// write individual values
	csv.write("foo", "bar");

My personal opinion on what nice JSON looks like:

• Scalars as per normal
• Empty objects/arrays as {} or []
• Single-entry objects on a single line if value is single-line
• Single-entry arrays are just wrapped in [...] (even if value is not single-line)
• Arrays <= 5 items on a single line if all values are single-line
• JSON.stringify() style indenting otherwise

Indenting customisable, but defaults to tabs - I code in proportional font, so four-space looks a bit narrow, and two-space just looks ridiculous.
