First change for the next post - better neighbour detection
Don't crash if agents get near the edge of the screen
Make obstacles 2x2 to decrease the occurence of the equal paths issue.
Should write something about flow fields with formations, even though it is sort of obvious how it'd work (formation steering behaviour)
Add steeringBehaviourLowestCost to cludge around the equal paths issue (described in the next blog post)
Revert the resolution double as it is no longer required
Add the next article - Making our flow field a bit better. Next up: Making our flow field even more better!
