  * This header file contains declarations for two utility
  * functions.  The first, which converts an integer to an apstring, is
  * from Part II of the AP Marine Biology Case Study.  The second,
  * which sorts a vector of fish based on their depth in the aquarium,
  * is loosely based on a similar function in Part II of the Case
  * Study.

  *    The IntToString function is the same as that found in Part II of
  *    the Case Study.  The SortByDepth function is similar to the sort
  *    function found there.
