/* CSVRead.java
 
   A simple demonstration of reading a CSV file and converting it
   to a Java data array, usable in a Java program. We're just
   printing out the data after loading it into a Java object here.

   The companion file Example.csv gives some sample data that can
   be used when testing this or other csv reader programs.
