Doubly linked lists

Normal classes:

DLIterC	Double linked list iterator.
DListC	Double linked List
ConstDLIterC	Constant iterator.
StringListC	List of StringC's
SubStringListC	List of SubStringC's

Normal functions:

operator <<(ostream &,const DListBodyC &)
operator >>(istream &,DListBodyC &)
operator <<(BinOStreamC &,const DListBodyC &)
operator >>(BinIStreamC &,DListC &)	Double linked List
operator <<(ostream &,const StringListC &)
operator <<(ostream &,const SubStringListC &)

Advanced classes:

DLinkC	Double-link element.
DLinkDataC	Double-link list element with data.
DLinkHeadC	Double-link list head.
IntrDListC	Double-linked circular list
IntrDLIterC	Intrinsic list iterator.

Advanced functions:

operator <<(ostream &,const IntrDListC &)

Double-linked circular list

Develop classes:

DListBodyC

Double linked list body.

Develop functions:

operator >>(BinIStreamC &,DListBodyC &)	Double linked list body.
operator <<(ostream &,const DListC &)	Send to stream.
operator >>(istream &,DListC &)	Read from stream.
operator <<(BinOStreamC &,const DListC &)	Write to a binary stream.
