-While I've been studying for programming interviews, I started thinking
-about how this Online Python Tutor could be a good resource for asking
-Programming Interview style questions and visualizing/debugging the
-answers.
-
-In order to do a good job, we'd want to create a special LinkedList
-class and render it in a special way (e.g., draw pointers to the MIDDLE
-of linked lists, etc.) ... and maybe even a BinaryTree or Graph classes
-if we're more ambitious.  Otherwise, the default rendering SUCKS for
-those types of programming interview style questions.
