      * pieces in a holder will usually have something in common, as decided
      * by the user. For example, they might represent sky, skyline, water or
      * other parts of the picture. In any large puzzle, there is a default
      * holder called "Hand", which represents a player collecting pieces in
      * his or her hand, then moving to the solution area to place them.
      *
      * The class has methods to assist in collecting and organizing pieces.
