+
+Retrieves circulation rule attributes that apply to the given
+branch and patron category, regardless of item type.
+The return value is a hashref containing the following key:
+
+maxissueqty - maximum number of loans that a
+patron of the given category can have at the given
+branch. If the value is undef, no limit.
+
+This will first check for a specific branch and
+category match from branch_borrower_circ_rules.
+
+If no rule is found, it will then check default_branch_circ_rules
+(same branch, default category). If no rule is found,
+it will then check default_borrower_circ_rules (default
+branch, same category), then failing that, default_circ_rules
+(default branch, default category).
+
+If no rule has been found in the database, it will default to
+the buillt in rule:
+
+maxissueqty - undef
+
+C<$branchcode> and C<$categorycode> should contain the
+literal branch code and patron category code, respectively - no
+wildcards.
