Timestamps:
0:00 Quadtree Part 2--query the data structure for points contained within a rectangular boundary
1:45 Write a query function to get all the points within a rectangle
3:16 Write an intersection function
6:14 Create an array of "found" points
13:00 Draw points within the rectangle
15:21 Sanity check--how many points are being counted
16:57 Adjust the rectangle with the mouse
18:44 Return the points array
19:42 Up next: apply the quadtrees algorithm to a collision detection problem
