cleanup repository (mainly remove the output)
cleanup bower components
add a makefile
massive reorganization

This is a precursor to adding epub support. Pandoc enforces
self-contained for epubs (makes sense), which in particular requires
us not to use relative paths.
improve the makefile

every file should be properly tracked now, so when
you run make only the changed files will be updated
Cleaned up all lecture chunks. TODO: scripts
Moved scripts to models.js
Updated README.md

Now reflects separation between Markdown files and the models.js that add dynamic content to HTML output. Added a few future plans
Moved to event-driven animation

Reduce CPU load by only rerendering when necessary, unless scene is
explicitly marked as “animated”. (This might only be a temporary
solution.)
