Create an input file for Fortran program HuntLS

Description

Program HuntLS reads an "outlier" raster created by program Align. The "outlier" k values indicate the number of interquartile ranges (q3-q1) a DoD de (delta elevation) value falls outside of the interquartile range: k = (de-q1)/(q3-a1) if k is less than q1 and k = (de-q3)/(q3-q1) if k is greater than q3. Values of de between q1 and q3 are given k values of zero. HuntLS associates k patches with field-mapped landslide locations surveyed for the Post Mortem (Stewart et al., 2013) study.
