Notes for beamer class handling
Some tests for slide and article containers (and some problems)
TODOs for the problems
Remove header-ish cruft; fix glossary calls to avoid redundancy
Slideshow container for Day 1; full article container
Move full article container into its own directory
Move two image files that now belong to day 2
Rename article.org to full-article.org

When the .tex file was called "article," it would generate a
glossary file "article.cls." This prevented xelatex from finding
the article document class definition, breaking compilation.
This doesn't happen when the glossary file is "full-article.cls."
Article container must look to parent dir for header and glossary
Modify image paths for compatibility between slideshows and article
