Description:

Truncate multiple Gaussian fields according to thresholds that
can vary locally.

Parameters:

gausfl: input data file with the Gaussian realizations that will
be truncated to create categorical variable realizations.

outfl: output data file for categorical variable realizations.

nsim: number of realizations

nx, ny, and nz: size of the simulation grid

ncat: number of categories

cat() and proportion(): the integer codes for each
category and its corresponding global proportion

pcurve: if set to 0 then there are no proportion curves and the
global proportions are used to establish the thresholds for
truncation. If set to 1, then proportion curve files are
considered for locally varying thresholds. ncat1 proportion
files are needed:

propfl: file containing a regular 3D grid (same size as the
input Gaussian realizations) containing the local proportions of the
ncat1 categories.

icolprop: column with locally varying proportion
