print_time_left(act_step, tot_step)

function print_time_left(act_step, tot_step)

% print_time_left(act_step,tot_step) prints the remaining time in a
% computation when act_step steps out of tot_steps have been made.
%
% A "tic" must have been called at the beginnig of the computation. This
% code must be called at the end of the step act_step (and not at the
% beginning).
%
% To reduce the computaton overhead, the code will only be active if
% floor(percentage) has changed in the last step (this can easy be
% removed by deleting the first 'if' condition).
