%description
Generalizes application of gray-level co-occurrence matrix (GLCM) metrics
to objects outside of images. The current focus is to apply GLCM metrics
to the study of biological networks and fitness landscapes that are used
in studying evolutionary medicine and biology, particularly the evolution
of cancer resistance. The package was developed as part of the author's
publication in Physics in Medicine and Biology Barker-Clarke et al. (2023)
<doi:10.1088/1361-6560/ace305>. A general reference to learn more about
mathematical oncology can be found at Rockne et al. (2019)
<doi:10.1088/1478-3975/ab1a09>.
