log: Add notes for Tuesday
proposal: Use the biblatex reference pacakge

This replaces 'cite', a less power reference package, which was only
being used because I couldn't get biblatex to build. Documentation:

http://ctan.mirrorcatalogs.com/macros/latex/exptl/biblatex/doc/biblatex.pdf
Add a common Makefile for LaTeX documents

This patch refactors the common boilerplate from LaTeX Makefiles into a
single common one which can be sourced by directories containing LaTeX
documents. It requires that the sourcing Makefile defines the
$(Document) and $(DocumentSources) variables, and provides targets for
wc, help, open, and cite. This greatly reduces the size of the build
system.
Add an empty research proposal summary document

Alan Bundy's IAD Course "Doing an Informatics PhD" requires a "a
1000 (+/- 100) word summary of your research project".
proposal: Add this afternoon's writing
Put 'proposal' dir inside of 'docs'

Let's keep everything together.
Include common Makefile in top-level Makefile
Build in parallel by default

This adds a "-j(n+1)" argument to the MAKEFLAGS variable, whether n is
the number of logical processors available, reported by nproc.
