/** @name Macros for definition of dynamic arrays and lists 

  These macros are ugly (especially if you look in the sources ;-), but they

  <BR>
  <BR>
  Range checking is performed in debug build for both arrays and lists. Type
  checking is done at compile-time. Warning: arrays <I>never</I> shrink, they
  only grow, so loading 10 millions in an array only to delete them 2 lines
  below is <I>not</I> recommended. However, it does free memory when it's 
  destroyed, so if you destroy array also, it's ok.

   This macro generates a new list class which owns the objects it contains,

   <BR>
   Don't use this for simple types such as "int" or "long"!
   You _may_ use it for "double" but it's awfully inefficient.
   <BR>
   <BR>
   Note on Add/Insert functions:
   <BR>
    1) function(T*) gives the object to the list, i.e. it will delete the
       object when it's removed or in the list's dtor
   <BR>
    2) function(T&) will create a copy of the object and work with it
   <BR>
   <BR>
   Also:
   <BR>
    1) Remove() will delete the object after removing it from the list
   <BR>
    2) Detach() just removes the object from the list (returning pointer to it)
   <BR>
   <BR>
   NB1: Base type T should have an accessible copy ctor  if  Add(T&) is used,
   <BR>
   NB2: Never ever cast a list to it's base type: as dtor is <B>not</B> virtual 
        it will provoke memory leaks
   <BR>

   some functions of this class are not inline, so it takes some space to 
   define new class from this template.

	271	<BR>
	272	Note on Add/Insert functions:
	273	<BR>
	274	1) function(T*) gives the object to the list, i.e. it will delete the
	275	object when it's removed or in the list's dtor
	276	<BR>
	277	2) function(T&) will create a copy of the object and work with it
278	<BR>
279	<BR>
280	Also:
281	<BR>
282	1) Remove() will delete the object after removing it from the list
283	<BR>
284	2) Detach() just removes the object from the list (returning pointer to it)
285	<BR>
286	<BR>
287	NB1: Base type T should have an accessible copy ctor if Add(T&) is used,
