C !DESCRIPTION: \bv
C *==========================================================*
C | SUBROUTINE OFFLINE_FIELDS_LOAD
C | o Control reading of fields from external source.
C *==========================================================*
C | Offline External source field loading routine.
C | This routine is called every time we want to
C | load a a set of external fields. The routine decides
C | which fields to load and then reads them in.
C | This routine needs to be customised for particular
C | experiments.
C | Notes
C | =====
C | currently the file names need to be specific lengths
C | would like to make this more flexible QQ
