! reading mechanism revised (subdomain/total domain size can vary arbitrarily

! former file user_interface.f90 split into one file per subroutine
!
! Description:
! ------------
! Reading restart data from file(s)
! Subdomain index limits on file are given by nxl_on_file, etc.
! Indices nxlc, etc. indicate the range of gridpoints to be mapped from the
! subdomain on file (f) to the subdomain of the current PE (c). They have been
! calculated in routine read_3d_binary.
