  Description
 
  The CMapStringToString class supports maps of CString objects keyed by
  CString objects.
 
  The member functions of CMapStringToString 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 CObject pointer as a return value or
  "output" function parameter, substitute a pointer to char. Wherever you
  see a CObject pointer as an "input" function parameter, substitute a
  pointer to char.
 
  BOOL CMapStringToOb::Lookup( const char* <key>,
                               CObject*& <rValue> ) const;
 
  for example, translates to
 
  BOOL CMapStringToString::Lookup( const char* <key>,
                                   CString& <rValue> ) const;
 
  CMapStringToString 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 CString-CString elements, you must set
  the depth of the dump context to 1 or greater.
 
  When a CMapStringToString object is deleted, or when its elements are
  removed, the CString objects are removed as appropriate.

  Public Members
 
  Construction/Destruction
 
  ◄CMapStringToString►   Constructs a collection that maps CString objects
                         to CString objects.
 
  ◄~CMapStringToString►   Destroys a CMapStringToString object.
 
  Operations
 
  ◄Lookup►             Returns a CString, using a CString 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).
