Fixes [YOCTO #2808]
I extracted the section that takes a closer look at the YP
development process into its own chapter. Feedback during the
review indicated that this information should not be buried as
it was in a section but rather pulled higher out for visibility.
So, The changes create a new chapter three that is dedicated to
this topic.
