Detailed Description

List item implementation.

This class implements one item of the list. In truth it implements the list itself. This class has all needed methods to make the useful list, a small problem is a head of list you must store somewhere and manage by yourself. Another problem: in the same list there can be items of different types, all inherited from ListItem class. There is no typechecking, too. It is better to use List template for list of items of concrete type. Direct descendants, same classes as ListItem class but with different names, are L1, LI2 etc. classes. They are usually used when inheriting a descendant from two or more ListItem classes (eg. if you want to use one object in two different lists).
