=item BornameSearch

  ($count, $borrowers) = &BornameSearch($env, $searchstring, $type);

Looks up patrons (borrowers) by name.

C<$env> is ignored.

BUGFIX 499: C<$type> is now used to determine type of search.
if $type is "simple", search is performed on the first letter of the
surname only.

C<$searchstring> is a space-separated list of search terms. Each term
must match the beginning a borrower's surname, first name, or other
name.

C<&BornameSearch> returns a two-element list. C<$borrowers> is a
reference-to-array; each element is a reference-to-hash, whose keys
are the fields of the C<borrowers> table in the Koha database.
C<$count> is the number of elements in C<$borrowers>.

C<&getmember> returns a reference-to-hash whose keys are the fields of
