- for obtaining set entries from a boolList
- BitOps::select to mirror bitSet constructor but returning a boolList
- BitOps::set/unset for boolList
ENH: construct bitSet from a labelRange
- useful, for example, when marking up patch slices
ENH: ListOps methods
- ListOps::count_if to mirror std::count_if but with list indexing.
- ListOps::find_if to mirror std::find_if but with list indexing.
ENH: UPtrList::test() method.
- includes bounds checks, which means it can be used in more places
(eg, even if the storage is empty).
