 ;Description: Get OEF/OIF conflict information for a patient
 ;Input:
 ;  DFN - Patient IEN
 ;  SORT - 1 to return array by location, 0 to return array by item
 ;       - 2 to return array by location and date
 ;  IGNORE - ien of 2.3215 sub-node ien to ignore
 ;  LOCK = 1 to ignore 'locked' entries
 ;Output:     
 ;  DGOEIF - the OEF/OIF conflict array, passed by reference
 ;   subscripts:
 ;   "COUNT"    Total # of entries in the multiple
 ;   "LAST"     The latest episode 'TO' date ^ related OEF/OIF/ UNKNOWN
 ;                 OEF/OIF code (1,2,3,4)^ien of multiple entry ^
 ;                 'FROM' date
 ;
 ;  For each entry in the multiple if SORT=0 (n is sequence of the item)
 ;   "LOC",n      Conflict Location
 ;   "FR",n       From Date
 ;   "TO",n       To Date
 ;   "LOCK",n     Locked Flag
 ;   "SITE",n     Data Source if from site
 ;   "IEN",n      IEN of the multiple entry
 ;
 ;  For each entry in the multiple if SORT=1 (n is the instance of the
 ;    item within the conflict)
 ;  For each entry in the multiple if SORT=2 (n is the from date of the
 ;    item)
