Initialise the fields from the initial g, just uses the fields_implicit routine
subroutine init_allfields_local
use fields_implicit, only: init_allfields_implicit
implicit none
!EGH Note that this will fail if someone has set
! the parameter new_field_init in init_g to .false.
! Add a warning/check?
call init_allfields_implicit
end subroutine init_allfields_local
