-	Parses CSV files including all subtleties such as:
-		* commas in fields
-		* double quotes in fields
-		* embedded newlines in fields
-			- Examples of programs that produce such beasts include
-			  MySQL and Excel
-
-	For a higher-level, friendlier CSV class with many conveniences,
-	see DataTable (which uses this class for its parsing).
-
-	Example:
-		records = []
-		parse = CSVParser().parse
-		for line in lines:
-			results = parse(line)
-			if results is not None:
-				records.append(results)

-	C-extension, csv:
-		http://www.object-craft.com.au/projects/csv/
-
-	It would be nice to use the csv module when present, since it is
-	substantially faster. Before that can be done, it needs to support
-	allowComments and stripWhitespace, and pass the TestCSVParser.py
-	test suite.
