Get the tag and subfield used to store the heading type
for indexing purposes. The C<$auth_type> parameter is
optional; if it is not supplied, assume ''.
This routine searches the MARC authority framework
for the tag and subfield whose kohafield is
C; if no such field is
defined in the framework, default to the hardcoded value
specific to the MARC format.
