    Index a polygon by it's bounding box

    Index a polygon by it's bounding box

    xmin

    min x value in xBounds

    ymin

    min y value in yBounds

    xmax

    max x value in xBounds, must be >= xmin

    ymax

    max y value in yBounds, must be >= ymin

    lenient

    standardize boundaries to valid values, or raise an exception

    returns

    z value for the bounding box
