% 	Lists in RECVAR
% 	---------------
%
% Management of lists.
%
% The lists can contain arbitrary data types (except sparse matrices) 
% as elements.
%
% Examples:
%
%	>> l1 = put1stl(5,[]);
%	>> l1 = put1stl(6,l1);
%	>> showl(l1)
%
% 		6
% 		5
%
%	>> l = makelist([1 2; 3 4], 5, 'hallo');
%	>> l = appendl(l,4);
%	>> showl(l)
%
% 		[1 2; 3 4]
% 		5
%		hallo
% 		4
%
%	>> a = setr([],'name','Tom');
%	>> a = setr(a,'age',43);
%	>> b = setr([],'name','Julia');
%	>> b = setr(b,'age',39);
%	>> MM = zerosm([2 2 2]);
%	>> MM = setm(MM,[1 2; 3 4], 1:2, ':', 1);
%	>> MM = setm(MM,[5 6; 7 8], ':', ':', 2);
%	>> register = setr([],'Type','Personel register');
%	>> personlist = makelist(a,b);
%	>> register = setr(register,'persons',personlist);
%	
%	>> l5 = makelist('hallo', [1 2; 3 4], [1; 2.5 + 3.75*i],a ,MM ,register);
%	>> dispr(l5)
%	
%		...
%
%
%
% The following functions are currently implemented:
% makelist	: Creates a list.
% put1stl	: Put an element first in the list. Can also create a list.
% appendl	: Appends an element last in the list.
% get1stl	: Gets the first element of a list.
% getrestl	: Returns a list with the first element removed.
% islastl	: Returns true if a list contains only one element.
% islist	: Returns true if the input parameter is a list.
% reversel	: Reverses the elements of a list.
% showl		: Shows the contents av all elements in a list on the screen.
% list2rec	: Converts a list to a record variable (Matlab 5 only).
%
% There is also new function "dispr" for the display the contents of a 
% variable on the screen. This function handles ordinary Matlab variables, 
% record variables, multidimensional matrices and lists.
%
% As an example of the use of list functions, the code for showl is below.:
%	 function showl(list)
%	 while (~islastl(list))
%	   disp(get1stl(list))
%	   list = getrestl(list);
%	 end%while
%	 disp(get1stl(list))
%
%Matlab 4:
%---------
% There are the same restrictions on the allowed operations on a list as
% on a record variable, since lists are implemented using record 
% variables. See help recvar.
%
%Matlab 5:
%---------
% Lists are implemented using Matlab 5's cell arrays, se reference [1].
