mdarray-jcsv (rubygems): MDArray-jCSV (jCSV for short) is the first and only (as far as I know)  multidimensional CSV reader.  Multidimensional? Yes... jCSV can read multidimensional data,  also known sometimes as 'panel data'. jCSV is based on Super CSV  (http://super-csv.github.io/super-csv/index.html), a java CSV library.  According to  Super CSV web page its motivation is 'for Super CSV is to be  the foremost, fastest, and most programmer-friendly, free CSV package for Java'. jCSV  motivation is to bring this view to the Ruby world, and since we are in Ruby, make it even easier and more programmer-friendly.
