title: circle-AABB containment test
body: <p>I'm currently in the throes of writing a system based on subdividing space (it's for a game), I need to be able to test if a circle completely contains a square.</p>
  
  <p>For bonus points, I should point out that my system works in N dimensions, so if your algorithm works by looping through each dimension and doing something, present it as such ;)</p>
