* improve example gui. Add simple pages * return old progress bar with example * base progress with steps, there is bug with step? 1 ~= 1, small delta? * polish progress, check float error case * add callback on end of "to" function, value check * start of green/red in progress * add first version of rich progress bar * make green bar darker * rich bar fixes * add delay, before filling in rich progress * PR fixes * remove dublicate of 'progress_rich'
