1551 Get the tag and subfield used to store the heading type
1552 for indexing purposes.  The C<$auth_type> parameter is
1553 optional; if it is not supplied, assume ''.

1555 This routine searches the MARC authority framework
1556 for the tag and subfield whose kohafield is
1557 C<auth_header.authtypecode>; if no such field is
1558 defined in the framework, default to the hardcoded value
1559 specific to the MARC format.
