Each call to StdOut. To that end, we have also accounted for the possibility that there are no headers, and data must be divined from column position. It would be used for such things as a method that prints out something. Read and write from a File.

The last thing to notice is that as long as new column positions are added to the end of the file and these are all new tracks, they will all be placed in the variable "tracks" because the column position definition from the CsvBindAndJoinByPosition annotation defines an open range starting at index 7.

Romanda contributed several fixes.
