Description: Functions for estimating the gliding box
    lacunarity (GBL), covariance, and pair-correlation of a random closed
    set (RACS) in 2D from a binary coverage map (e.g. presence-absence
    land cover maps).  Contains a number of newly-developed
    covariance-based estimators of GBL (Hingee et al., 2019)
    <doi:10.1007/s13253-019-00351-9> and balanced estimators, proposed by
    Picka (2000) <http://www.jstor.org/stable/1428408>, for covariance,
    centred covariance, and pair-correlation.  Also contains methods for
    estimating contagion-like properties of RACS and simulating 2D Boolean
    models.  Binary coverage maps are usually represented as raster images
    with pixel values of TRUE, FALSE or NA, with NA representing
    unobserved pixels.  A demo for extracting such a binary map from a
    geospatial data format is provided.  Binary maps may also be
    represented using polygonal sets as the foreground, however for most
    computations such maps are converted into raster images.  The package
    is based on research conducted during the author's PhD studies.
