//   * Lines will be separated by the platform-specific EOL terminator.
//   * Values will be enclosed in double-quotes if and only if they contain
//     either of the following characters: CR, LF, double-quote ("), comma (,).

// which is first cleared of pre-existing data. The first line of the file will
// contain |column_names|, followed by as many lines as there are elements in
// |records|. Each element in |records| should be a dictionary that maps column
// names to values, so they can be output in the right order. All passed in
// strings should be UTF-8 encoded.
