  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.
