Make each chapter introduction stand out (#179)

* Add bibliography to the ToC

* Add a list of tables at the end of the document

It needed shorter description that would fit.

* Add list of figures

* Add table of figures

* Fix a typo in short figure description

* Make each chapter introduction stand out

Not written for each chapter yet, but checking if that is something we
want.

* Increase numwidth in list of figures

Prevents over-run of figure number and text

* Use semibold in chapters intro

Looks like a good compromise for now.

* Add comments

* Add color coding to flow charts

This will hopefully allow easier reading by identifying start and end
point more easily
