e and
% generate a new tree holding the result. For instance:

t = lineage.subtree(19);
letterCount = t.treefun(@numel);
disp( [t.tostring letterCount.tostring ] ) % Count the number of letters in each string of the t tree

%%
% *|treefun2|* does the same, but with two trees and a 2-arguments function:

lastLetter = t.treefun2(letterCount, @(a, b) a(b));
disp(lastLetter.tostring) % Extract the last letter





%% Misc functions
