/** Candidate main program
 *
 *  This program does the usual open and close of files using the DABUtils methods,
 *  and then it reads the file into an ArrayList and echoes the ArrayList to the
 *  console.
 *
 *  The main difference between this program and the previous program is that in
 *  this program we use in CandidateList3 an ArrayList whose elements are
 *  themselves instances of the Candidate class.  In the previous versions we
 *  read in the data as a complete line of text but did not in fact parse that
 *  text to make any sense of it.  The Candidate class implements a "record"
 *  of multiple "fields" for name, party, and such.  This permits the data to be
 *  searched and manipulated by field directly.
 *
 *  (One could, of course, continue to save the data simply as a single text
 *  string and then implement a search by field by parsing the strings every time.
 *  That, however, is not what is usually done in handling data.)
