Changed the formatting of the pre tags in chapter 6. The content wasn't changed in any way, but I made the code look a little cleaner.

             The Java <c>for</c> loop is really analogous to the last option giving you explicit control over the starting, stopping, and stepping in the three clauses inside the parenthesis.
             You can think of it this way:
         </p>

-    statement1
-    statement2
-    ...
-}</pre>

             If you want to start at 100, stop at 0 and count backward by 5, the Python loop would be written as:
