module state_point
!===============================================================================
! STATE_POINT -- This module handles writing and reading binary state point
! files. State points are contain complete tally results, source sites, and
! various other data. They can be used to restart a run or to reconstruct
! confidence intervals for tallies (this requires post-processing via Python
! scripts).
!
! Modifications to this module should be made with care. There are essentially
! three different ways to write or read state points: 1) normal Fortran file
! I/O, 2) MPI-IO, and 3) HDF5. The HDF5 functionality is contained in the
! hdf5_interface module. If you plan to change the state point, you will need to
! change all methods. You should also increment REVISION_STATEPOINT in the
! constants module.
!
! State points can be written at any batch during a simulation, or at specified
! intervals, using the <state_point ... /> tag.
