// Class: SoAuditorList
//
// SoAuditorList class. This class maintains a list of instances that
// audit (receive notification from) an SoBase or SoField. Each entry
// in the list consists of a pointer to the auditor (base or field)
// instance and a type code of type SoNotRec::Type.
//
// The type of the auditor object pointer depends on the type code,
// as follows:
//
// Type code: Auditor object pointer:
//
// CONTAINER The SoFieldContainer containing the field
// PARENT The parent node
// SENSOR The SoDataSensor instance
// FIELD The destination field instance
// ENGINE The destination field instance
//
// Since there are two entries in the underlying SbPList for each
// auditor, some of these methods have to do some fancy footwork.
//
