Update the seeds file for different simulations automatic in the new version of ALF
If simulations of different parameters shared same initial seeds file. Since they took identical sequence of random numbers,there would be inter-correlation between different data points. Of course, the inter-correlation should decay with the distance and simulation time. But this is model dependent, sometimes it is much longer than the warming up time. So it will be convenient for us to update the seeds file for different simulations automatic in the new version of ALF.
