This week you are to modify your quadtree program to add the capability to interactively delete entered points. The program should work as last week in response to the left mouse button, but if the right mouse button is clicked on a previously entered point, it should delete that point. A right mouse click that is not on a previously entered point should be ignored. Of course, the quadtree should be redisplayed to reflect its new configuration after each enter or delete. The program should not quit until either the 'q' or 'esc' key is pressed on the keyboard. I will demonstrate how the program should work in class.
Please submit your program using the standard submit procedure. You should include your program source code and a Makefile.
