This is a very simple class, principally used to sum up total values inside annuli in a fixed resolution buffer. It accepts fixed_buffer, which should be a FixedResolutionBuffer, center, which is in pixel coordinates. num_bins, min_radius and max_radius all refer to the binning properties for the annuli. Note that these are all in pixel values.
