- makes fileHandler calling resemble Time more closely
ENH: provide natural_sort less/greater functions
- more succinct than (compare < 0) or (compare > 0).
The corresponding wrappers for UList renamed as list_less, etc
but they were only used in unit tests
ENH: handle (-allRegions | -all-regions, ..) directly when retrieving args
- makes handling independent of aliasing order
STYLE: include <string_view> when including <string>
- the standard does not guarantee which headers (if any) actually
include string_view
- extend the getAllRegionOptions and getAllFaRegionOptions handling
to use the supplied string literals as fallback values.
If regionProperties is missing (or empty) and the -regions/-area-regions
option is supplied with literal names, these will be used directly
instead of being used to filter the regionProperties.
STYLE: support both -all-regions and -allRegions
