Code generator - Recognise group OCCURS

[pgmitche]

Example:

000990         10  GROUP.                           00000240
000990            15  PROP-A       PIC 9(9).9(2).         00000241
000990            15  PROP-B       PIC X.                      00000254
000990                OCCURS 12.                                  00000242

Where the occurrence is of GROUP-A, not PROP-B

and should produce

type stuff struct {
     Groups []Group `pic:"x,y,z"`
}

type Group struct {
     PropA float64 `pic:"x,y,z"`
     PropB string `pic:"x,y,z"`
}
