[OPEN-ILS-GENERAL] Evergreen MARC record / holdings batch loader

[David Christensen]

Hi Dan,

Thanks for taking a look :-)

Here are the updated files.   I *really* appreciate the distinction you made
between TCN and record_id - that was something that gave me no end of
confusion :-)

As far as Vandelay... just bad timing on my part :-/   I'm just now hearing
about it (that will teach me to stick my head in the sand!); I'm quite
excited by the prospect.  If nothing else, though, monkeying with these
batch-loading scripts helped me to understand the system more :-D

Thanks again - I appreciate the feedback.
