Used to mark a property or field that reference an object for which database
 fields need to be loaded. The referenced object then contain fields or properties 
 marked with FieldMappingAttribute.
 The field must be marked on a reference type field not a value based field.
 This attribute is useful in situations where another class (usually an inner class) 
 holds a reference to an object that contains additional properties that are stored
 in the same record as the main container class.
