The population passed to callbacks is not human-readable.

Hi @framp , thanks for building this great library!

I was playing around a bit and I found it is hard to debug the results since the population passed to callbacks (meta.pop member) is untabled. I propose a change that adds one more member (meta.popTables) where each entity is in form of a timetable. It's a very simple change and I've tested it in alenl/timetabling-solver@f970379 . Would you take a PR on it? If you are interested, I'll prepare it.

Hi @alenl, glad you're liking the library!

I think it can work out, if it's behind a debug flag: some of the places where this function is being used are already quite slow and I wouldn't want to add another bookables * populationElements loop on top of it

Sure thing, I'll add that and make a PR.
Are you interested in other PRs?

Really appreciated!

There are a couple optimisation/improvements here:
#1

Also open to ideas and to discuss what more can we add / improve
(the original idea was to provide solvers for other timetabling problems as well, not only mininum collisions but I never had the actual need for it)
