75 Takes a comma-delimited CSV-style string argument and returns the kind of data structure that Koha::Patron->extended_attributes wants,
76 namely a reference to array of hashrefs like:
77 [ { code => 'CODE', attribute => 'value' }, { code => 'CODE2', attribute => 'othervalue' } ... ]
79 Caches Text::CSV parser object for efficiency.

106 Takes three arguments. The first two are references to array of hashrefs, each like:
107 [ { code => 'CODE', value => 'value' }, { code => 'CODE2', value => 'othervalue' } ... ]
109 The third option specifies whether repeatable codes are clobbered or collected. True for non-clobber.
111 Returns one reference to (merged) array of hashref.
113 Caches results of C4::Members::AttributeTypes::GetAttributeTypes_hashref(1) for efficiency.
