+  adds an authority entry in the db.
+  It calculates the level of the authority with the authoritysep and the complete hierarchy.
+
+C<$dbh> is a DBI::db handle for the Koha database.
+
+C<$hash> is a hash containing freelib,stdlib,category and father.

+
+  searches for an authority
+
+C<$dbh> is a DBI::db handle for the Koha database.
+
+C<$category> is the category of the authority
+
+C<$toponly> if set, returns only one level of entries. If unset, returns the main level and the sub entries.
+
+C<$branch> can contain a branch hierarchy. For example, if C<$branch> contains 1024|2345, SearchAuthority will return only
+entries beginning by 1024|2345
+
+C<$searchstring> contains a string. Only entries beginning by C<$searchstring> are returned
