Re: delete_subfields()

[moregan]

MARC::Field->as_string() takes a string of subfields rather than an array.
It would be better for as_string() and delete_subfields() to have the same
interface.  Since as_string() is used a lot in production,
delete_subfields() should be the one to change.

Jackie Shieh at Univ of Michigan thought it would be handy to have a
delete_subfields() method on MARC::Field objects. Basically the
method takes a list of subfields to delete, and deletes each one,
returning the total subfields that were removed. If a subfield
repeats all of them are deleted.

    $field->delete_subfields( 'z' );

I've committed the new method and a few tests to SourceForge if
anyone is interested in taking a look. [1]
