user limits and/or infinite absorber for specific elements
Issue #317
new
Would be good to be able to remove particles upon entry to certain volumes, for example, collimators (which already have collimatorsAreInfiniteAbsorbers
, but is a global tracking option)
This could be achieved by adding user tracking limits to specific elements or having more specialised options, for example absorption of a specific particle. The most general is user limits.
