When facts referred to auditor; on application and notice; on court's own motion

Upon application of either party, after notice to the opposite party, the judge of the superior court, in equitable proceedings if the case shall require it, may refer any part of the facts to an auditor to investigate and report the result to the court. Furthermore, the judge may, upon his own motion, when in his judgment the facts and circumstances of any such case require it, refer the same to an auditor.
