'popularity' is a way to sort bibliographic results of a search.

In the Zebra setup this sort is based on a value, the value of all loans done
with all items/copies of a specific bibliographic record.

In NoZebra setup the valuse is calucated every time with an SQL query on
loan data.

In Zebra setup the source of the data is the column biblioitems.totalissues of
the table biblioitems
To use popularity with zebra we need to transer the value in 
biblioitems.totalissues
to a specific subfield.

All is ok for MARC21 framework.
But not for unimarc framework
The two unimarc defintion that we have (french and english) say:
-- English: 990$0
-- French: 995$s

But 995 is the unimarc field for items, for the values of the table items.
The value of biblioitems.totalissues is connect with the bibliographic record,
not with items level.

But also the field 990 is used in French framewor for a different use.

So I will use 942$0 [as Marc21] and I will send a patch to use the subfield
942$0 as source of popularity index

The defintion file is ../etc/zebradb/marc_defs/unimarc/biblios/record.abs
