 * mlClasses, will create a new instance and add it to mlClasses.                  
 *
 * After talking to the user it has come to light that the first sub-directory in
 * a path will dictate what class he/she feels a image belongs to.
 *   Ex:
 *    .../Protista/
 *    .../Protista/SubDir1
 *    .../Trichodesmium
 *    .../Trichodesmium/SubDir1
 *    .../Trichodesmium/SubDir2
 *    
 *  The idea is that when trying to determine what class a image really is we look
 *  at the first sub-dir name in the path.  We may also have to deal with seq-num's 
 *  as part of the name,  in that case we strip the _ and following numbers from the 
 *  name to get the correct class name.
