WIP: won't fix issue #7

OK, so I have found the problem with #7 (closed), it is fixed now.

The most important commit is 03b25fc9

I think this line tried to optimize something, but instead it introduced an error.

If you can find out how to keep this line uncommented (to preserve this optimization which I removed) and find where is the problem with isMin and hasBB, then it would be great :)

Also I have added a new checkColliderByGiulia.py. It will make your life easier if you will want to find the problem with isMin and hasBB. You can also run it by hand, you only need to uncomment the input line and maybe uncomment some debug info.

All other stuff in this branch I only have done to make debugging easier. About some of this stuff (e.g. new cmake TRACEONLY option) I will write more in the documentation. For example now in checkList.py you can quickly enable debugging of only one --check script.

I have tested this in 7 chroots python3.
