% Tabling is also important for the memoisation it offers.
% The standard example is calculating Fibonacci numbers.
%
% As an example, this benchmark calculates the N-th Fibonacci number without tabling.
% You can compare its execution time to the version with tabling in fib-no-tabling-hprolog.pl

% This is also interesting for a paper (Marko, Tom).
