Added the monitoring facilities for snapshots (i.e. generating and plotting a new file

every generation) which is different from the continuous monitoring (same file/plot is
angemented every generation).
This lead to a number of modifications in many files in utils dir

But now we can watch on-line
- fitness spreadout
- FDC plots
- multi-objective Pareto fronts (though the multi-objective sruff isn't there yet!)
