Preliminary work on marc21_field_008.pl and 008_authorities.pl.
Moving $dateentered en $defaultval to lower scope level.
date_entered is a new sub (in a module); sub Field008 has been reduced to
one line.
Added a trivial unit test for date_entered.
Note: the format used in date_entered could be added in DateUtils, moving
this logic to a better place.
Test plan:
Use both plugins in the marc21 editor (biblios/authorities).
Run the adjusted unit test.
