Implement sampling vertices from subtractions

[gipert]

Useful to simulate e.g. K42 decays outside mini-shroud but inside cylinder.

I'm not sure what I meant here, but this seems to me already supported.

[ManuelHu]

I suppose you meant "from a substraction of two user-defined solids" (i.e. where none of them is from the original geometry). This is not yet possible

[gipert]

Ah yes you are right...

[tdixon97]

do we really need this? whats the application? E..g LAr inside MS can be simulated already

[gipert]

LAr outside MS?

[tdixon97]

Yes I get it now what you want is to select points where A & !B compared to what you have now which is A& B. Although thats slightly different to what Manuel suggested above.
Do we really want to add more features to the RMG generators though, or move to python entirely? For me its seems much easier, and better to do it sooner. Although this is probably really easy to implement (but harder to test in c++)

[gipert]

In C++ we have ::IsInside(), that's quite crucial...

Ok now I am remembering this discussion. I will work on this implementation and meanwhile think of some high level tests we can do.
