Various minor edits, mainly typos.
Added new lab called FourierExtensions.
This time I actually added the new files...
add more whitespace between paragraphs

Also pad the problem boxes so they look less crowded.

We add extra space between paragraphs to give a less dense feel of the
text material.  The space is minimal so it doesn't inflate the total
page count by too much.  It helps the labs read easier.
Added images to the lab, including the plotFigs file.
