multiPlot statistic

[dejan86p]

Can you add statistic for multiple plots in file( -n 45 )
its easier to get stats.
i added something like this but you will do way better than me.
const std::time_t starttime = time(0);

                   int diff = 0;
	       float averangeplottime = 0;
	       int currentplot = 0;
		std::time_t ttime = currenttime(0);
		Timediff = currenttime - starttime;
		currentplot = i + 1;
		averangeplottime = diff / currentplot;
		std::cout << "Plot " << currentplot << "/" << num_plots << std::endl;
		std::cout << "seconds from start " << Timediff << std::endl;
		std::cout << "Averange seconds per plot " << averangeplottime << std::endl;
