OUTPUT format for OMGEANT

 One can write several GEANT banks to the output in FZ (ZEBRA) format.
 Writing is triggered by the FF command:

 SAVE  'bnk1' 'bnk2' ....
 
 where bnk1 ... are the names of banks. One can specify GEANT banks
 like KINE, VERT etc.
 
 One OMGEANT bank can be written at the moment: OHIT
 this bank contains hit information of all tracks with all sensitive 
 media.

 The recommended way to write:

 SAVE 'KINE' 'VERT' 'OHIT'

 
                          OHIT format


C---      JOHITS    - a hit bank (special format - INTEGER/REAL values)

C                johtj=LQ(JOHITS-itrj)
C                    IQ(johtj+1) = itra (see JKINE)
C                    IQ(johtj+2) = nhits - number of stored hits (ihit=1,nhits)
C                        johth=LQ(johtj-ihit)

C                             For detectors:

C                   7:9  - 0
