Basic GAM/K algorithm: Part 1
do circle_RADIUS=min_RADIUS, max_RADIUS
do circle_X=min_X, max_X, circle_RADIUS*0.2
do circle_Y=min_Y, max_Y, circle_RADIUS*0.2
- get data for circle at (circle_X, circle_Y, circle_RADIUS)
- assess its significance
- if significant then write (circle_X, circle_Y, circle_RADIUS)
