  Description
 
  The CMapWordToOb class supports maps of CObject pointers keyed by 16-bit
  words.
 
  The member functions of CMapWordToOb are similar to the member functions
  of class CMapStringToOb. Because of this similarity, you can use the
  CMapStringToOb reference documentation for member function specifics.
  Wherever you see a CString or a const pointer to char as a function
  parameter or return value, substitute WORD.
 
  BOOL CMapStringToOb::Lookup( const char* <key>,
                               CObject*& <rValue> ) const;
 
  for example, translates to
 
  BOOL CMapWordToOb::Lookup( WORD <key>, CObject*& <rValue> ) const;
 
  CMapWordToOb incorporates the IMPLEMENT_SERIAL macro to support
  serialization and dumping of its elements. If a map is stored to an
  archive, either with the overloaded insertion operator or with the
  Serialize member function, each element is, in turn, serialized.
 
  If you need a dump of individual WORD-CObject elements, you must set the
  depth of the dump context to 1 or greater.
 
  When a CMapWordToOb object is deleted, or when its elements are removed,
  the CObject objects are deleted as appropriate.

  Construction/Destruction
 
  CMapWordToOb   Constructs a collection that maps words to CObject
                   pointers.
 
  ~CMapWordToOb   Destroys a CMapWordToOb object.
 
  Operations
 
  Lookup             Returns a CObject pointer, using a word value as a
                       key.
 
  SetAt              Inserts an element into the map; replaces an
                       existing element if a matching key is found.
 
  operator []        Inserts an element into the map──operator
                       substitution for SetAt.
 
  RemoveKey          Removes an element specified by a key.
 
  RemoveAll          Removes all the elements from this map.
 
  GetStartPosition   Returns the position of the first element.
 
  GetNextAssoc       Gets the next element for iterating.
 
  Status
 
  GetCount   Returns the number of elements in this map.
 
  IsEmpty    Tests for the empty-map condition (no elements).
