exp_variogram - compute variogram for a cornerpoint grid with properties.

       This  program  computes  data  for an experimental variogram from a cornerpoint geometry with properties.
       This works by choosing pairs of volumes chosen randomly, and comparing their distance with the difference
       in their properties (poro or perm). Direction for pairing is set from the command line.

ilen Length in i-direction of subsample, specified in number of  cells.  Defaults  to  all  cells  in  i-
       direction.
       jlen  Length  in  j-direction  of  subsample,  specified  in number of cells. Defaults to all cells in j-
       direction.
       zlen Length in z-direction of subsample, specified in the grids length unit (typically cm or m). Defaults
       to full height.
       imin Can be used to limit the search area for random subsamples. Defaults to minimum i in inputgrid (full
       model).
       imax Can be used to limit the search area for random subsamples. Defaults to maximum i in inputgrid (full
       model).
       jmin Analog to imin, but in j-direction. Defaults to minimum j in inputgrid (full model).
       jmax Analog to imax, but in j-direction. Defaults to maximum j in inputgrid (full model).
       zmin Analog to imin, but in z-direction and specified in the grids length unit. Defaults  to  minimum  in
       inputgrid.
       zmax  Analog  to  imax, but in z-direction and specified in the grids length unit. Defaults to maximum in
       inputgrid.
       pairs Number of pairs. Defaults to 100.
