# A Special is a Simulton; it updates by removing
#   any Hunter whose center is contained within its radius
#  (returning a set of all eaten simultons), and
#   displays as a black PacMan with a radius of 40
# Calling get_dimension for the width/height (for
#   containment and displaying) will facilitate
