!**** *DIST_SPEC* - Distribute global spectral array among processors

!     Purpose.
!     --------
!        Interface routine for distributing spectral array

!**   Interface.
!     ----------
!     CALL DIST__SPEC(...)

!     Explicit arguments : 
!     -------------------- 
!     PSPECG(:,:) - Global spectral array
!     KFDISTG     - Global number of fields to be distributed
!     KFROM(:)    - Processor resposible for distributing each field
!     KVSET(:)    - "B-Set" for each field
!     KRESOL      - resolution tag  which is required ,default is the
!                   first defined resulution (input)
!     PSPEC(:,:)  - Local spectral array
!
!     Method.
!     -------

!     Externals.  SET_RESOL   - set resolution
!     ----------  DIST_SPEC_CONTROL - control routine
