Description: This is an evolving and growing collection of tools for
        the quantification, assessment, and comparison of shape and
        pattern. This collection provides tools for: (1) the spatial
        decomposition of planar shapes using 'ShrinkShape' to
        incrementally shrink shapes to extinction while computing area,
        perimeter, and number of parts at each iteration of shrinking;
        the spectra of results are returned in graphic and tabular
        formats (Remmel 2015) <doi:10.1111/cag.12222>, (2) simulating
        landscape patterns, (3) provision of tools for estimating
        composition and configuration parameters from a categorical
        (binary) landscape map (grid) and then simulates a selected
        number of statistically similar landscapes. Class-focused
        pattern metrics are computed for each simulated map to produce
        empirical distributions against which statistical comparisons
        can be made. The code permits the analysis of single maps or
        pairs of maps (Remmel and Fortin 2013)
        <doi:10.1007/s10980-013-9905-x>, (4) counting the number of
        each first-order pattern element and converting that
        information into both frequency and empirical probability
        vectors (Remmel 2020) <doi:10.3390/e22040420>, and (5)
        computing the porosity of raster patches
        <doi:10.3390/su10103413>. NOTE: This is a consolidation of
        existing packages ('PatternClass', 'ShapePattern') to begin
        warehousing all shape and pattern code in a common package.
        Additional utility tools for handling data are provided and
        this package will be added to as more tools are created,
        cleaned-up, and documented.  Note that all future developments
        will appear in this package and that 'PatternClass' will
        eventually be archived.
