Improve efficiency

[oscarlvp]

Even when Descartes is several times faster than the default PIT engine it would be nice to improve the efficiency of the whole mutation analysis for practical use in regular development cycles.

Note that this issue was raised as a result of the workshop I did with Oscar on XWiki, see my blog post at http://massol.myxwiki.org/xwiki/bin/view/Blog/MutationTestingDescartes

This is more suited for PIT.

So I guess you're saying that the performance is not going to be improved (since you're not working on PIT). That's an issue for using Descartes in real life projects.
