  - Adds symmetric family for equality constraints of the potentials
    array.

                        Changes in version 0.5.1                        

  - Added vec_description() function to explicitly describe what
    relative positions and interactions are associated with each element
    of the summarized vector of parameters/sufficient statistics in each
    parameter restriction family.

                  Changes in version 0.5 (2020-10-29)                   

  - rpositions() can now be used as an alternative to create mrfi
    objects based on explicitly described relative positions with a
    simpler syntax than mrfi().
      - Added a vignette on analyzing 3d data via 2d projections in
        mrf2d.
      - Fixed bug that caused the R session to crash when calling
        smr_stat() with incomplete lattices.

                 Changes in version 0.4.1 (2020-10-20)                  

  - Added rmrf2d_mc to simplify the use of Monte-Carlo methods from

      - Minor documentation updates.

                         Changes in version 0.4                         

  - Added mrfout and hmrfout classes for model fitting functions output.
    A summary() and plot() methods are also available.
      - Simplified structure of documentation files.

  - Co-ocurrence histogram computing is now exported in the cohist()
    function.
      - Computing of conditional probabilities for individual positions
        are now exported in the cp_mrf2d() function.
      - All the conversions from/to arrays to/from vectors are now
        available. See the help file for smr_stat.
      - Additional example data included in field1 and hfield1.
      - Documentation improved, including paper available in:
