[Evogrid-dev] New milestones, new visualization utility

[Peter Newman]

We can, and currently there is 1000 GROMACS internal loops to each saved 
state. But at the moment I'm working with previously simulated 
histories, just to get the visualiser working. Once we have data that 
shows what we want, in this rough view, we can redo the run with finer 
state logging, I figure.

I agree, keeping human interest is important.
