Speed up

[mrx23dot]

It takes 2-3secs to do one query on 100lines,
and it takes multiple calls to one contract to get meaningfull info out.
So ~10secs/contract on i5, it could sure use some profiling :)

not sure when I'll have time to look into this but yeah, there's a lot of potential to speed things up. Especially for the GenericGrep rule. By analyzing the grep pattern we could shortcut a lot of unnecessary loops for example.
