I think I finally arrived at a good ordering of material.
Started with implementing a linear problem just so we can
see how it differs from the linear KF, then added problems
step by step. Got rid of most of the poor performing filters.
Added code to inject \appendix to the first appendix notebook
so that they are properly labelled. Started g-h chapter as chapter
one. There is probably a lot more I want to do now that I have
the basic idea of how to inject latex into the files before creating
the PDF, but this is a good start.
