HXL.foreach(filename, options, &block)
This reads a standard HXL encoded CSV and yields each row. The HXL class will use compact disaggregation to build the new CSV. Read more here.
HXL.concat([filenames], options, &block)
Concat takes a list of filenames and concats the HXL encoded files together, intelligently matching columns based on their HXL tag.
HXL.join([filenames], on, options, &block)
