- * delimited text is a very popular format for data interchange. It is\r
- * understood by most database, spreadsheet, and organizer programs.\r
- * <p>\r
- * Each row of text represents a row in a table or a data record. Each row\r
- * ends with a NEWLINE character. Each row contains one or more values.\r
- * Values are separated by commas. A value can contain any character except\r
- * for comma, unless is is wrapped in single quotes or double quotes.\r
- * <p>\r
- * The first row usually contains the names of the columns.\r
- * <p>\r
- * A comma delimited list can be converted into a JSONArray of JSONObjects.\r
- * The names for the elements in the JSONObjects can be taken from the names\r
- * in the first row.\r
