CSC 324: Assignment 4 clarifications

These clarafications and announcements were originally posted on the assignments page.

• Clarification: print_world should, for full marks, print a horizontal pictoral representation of the world, similar to the example. You may assume (and document) an upper limit to the length of a block name (perhaps something like less than the width of a tab) and you may assume the screen is wide enough to print your representation. And no, you don't need to print the table legs. :-)
• Note: For part I, the limit is 3 blocks directly on the table at any time. There is no limit to how tall a pile can be (except the number of blocks in the world). For part II, initialize_world defines how many piles can fit on the table, and piles again can be as tall as there are blocks.
• Note: Part II is an extension of the functionality of part I. You should provide place/2, on/2, and clear/1 predicates. The way you store the state of the world (in both parts) is up to you.
