Final feedback from Zoltan.
Fix a vim editor hint.
Fix figure placement in 2.1

Of two related figures one straddeled a page boundary.  Both figures are now
subfigures in the same larger figure.
Fix figure placement in Ch6.

Two sub figures were side-by-side but they fit better one above the other.
Fix over/under-ful h/v-boxes.

+ Add hypenation hints for some terms that did not have them
+ Use ragged right justification in the bibilography
+ Use the nowidow package to prevent widows and orphens.
Paginate figures.

Place figures near their discussion as much as is possible.
I've also added a page-break to prevent latex from breaking a page in the
middle of a small description environment.
