Tab Delimited File Format
How XYnk parses tab delimited files, which is a useful format for importing:
The first line of the file is intepreted as the headers for the columns.
Xynk interprets the first column in the file as the "Subjects" column, although it retains the header name from the file (i.e. the column will appear as "AID" in the measures view, but labeled as "Subject" in the data view.
Xynk expects to find at least a column with the heading "Group", which it uses to sort the rows into groups.
