[libpkg] - report #4

[David Forsythe]

I spent a good portion of this week reading about ways to make the
library more flexible to changes that could be coming into the package
system and looking at other package managers and their components.
I've redone my design, and I'm writing a bunch of code to make the
code in the library that was already good work with the new code.
This meant re-writing my property list structure and now re-writing my
plist parser to use it.  Some basic tests were written for the new
property list structure, and I'm currently going back and forth
between writing documentation and finishing the new parser.
