  Description
 
  The CStringArray class supports arrays of CString objects.
 
  The member functions of CStringArray are similar to the member functions
  of class CObArray. Because of this similarity, you can use the
  CObArray reference documentation for member function specifics. Wherever
  you see a CObject pointer as a return value, substitute a CString.
  Wherever you see a CObject pointer as a function parameter, substitute a
  const pointer to char.
 
  CObject* CObArray::GetAt( int <nIndex> ) const;
 
  for example, translates to
 
  CString CStringArray::GetAt( int <nIndex> ) const;
 
  and
 
  void SetAt( int <nIndex>, CObject* <newElement> )
 
  translates to
 
  void SetAt( int <nIndex>, const char* <newElement> )
 
  CStringArray incorporates the IMPLEMENT_SERIAL macro to support
  serialization and dumping of its elements. If an array of CStrings 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 string elements in the array, you must
  set the depth of the dump context to 1 or greater.
 
  When a CString array is deleted, or when its elements are removed,
  string memory is freed as appropriate.

  Public Members
 
  Construction/Destruction
 
  CStringArray   Constructs an empty array for CString objects.
 
  ~CStringArray   Destroys a CStringArray object.
 
  Bounds
 
  GetSize         Gets number of elements in this array.
 
  GetUpperBound   Returns the largest valid index.
 
  SetSize         Sets the number of elements to be contained in this
                    array.
 
  Operations
 
  FreeExtra   Frees all unused memory above the current upper bound.
 
  RemoveAll   Removes all the elements from this array.
 
  Element Access
 
  GetAt       Returns the value at a given index.
 
  SetAt       Sets the value for a given index; array not allowed to
                grow.
 
  ElementAt   Returns a temporary reference to the element pointer
                within the array.
 
  Growing the Array
 
  SetAtGrow   Sets the value for a given index, growing the array if
                necessary.
 
  Add         Adds an element to the end of the array; grows the array
                if necessary.
 
  Insertion/Removal
 
  InsertAt   Inserts an element (or all the elements in another array)
               at a specified index.
 
  RemoveAt   Removes an element at a specific index.
 
  Operators
 
  operator []   Sets or gets the element at the specified index.
