ASCII ProgresBar (included elapsed/estimated time)

Uses the command window to show a progress bar, plus how long the computation has taken, and the estimated time remaining. All on one line, so there's less flicker.

Example:

steps = 500;
progbar = progressBar(steps,'Rendering');

for tmp = 1:steps
progbar(tmp);
pause(.01)
end

Would probably work all the way back to matlab 6.5 if it didn't use multi-line comments in the description.
