Description: These functions provide procedures for selecting sites for spatial
    surveys using spatially balanced algorithms applied to discrete points,
    linear networks, or polygons. The probability survey designs available
    include independent random samples, stratified random samples, and unequal
    probability random samples (categorical or probability proportional to
    size).  Design-based estimation based on the results from surveys is
    available for estimating totals, means, quantiles, CDFs, and linear models.
    The analyses rely on package survey for most results.  Variance estimation
    options include a local neighborhood variance estimator that is appropriate
    for spatially-balanced survey designs.  A reference for the survey design
    portion of the package is: D. L. Stevens, Jr. and A. R. Olsen (2004),
