Text based progress bar

Faster than waitbar (MATLAB builtin)

N = 500000;

WB = waitbar(0,'waitbar');            % waitbar (MATLAB builtin)
for n = 1:N, waitbar(n/N,WB); end
close(WB)

PB = ProgressBar(N);                  % ProgressBar gui
for n = 1:N, PB.count; end

PB = ProgressBar(N, ui='cli');        % ProgressBar cli
for n = 1:N, PB.count; end
