- Created academic module, which holds the academic portion of the site.
- Wrote academic models and committed them to the database
- Updated models
- Added new templates for the academic section
- Pulled down previous website source to fill templates
- Moved base.html to a top-level directory
Updated course and course instance models. Filled the database with
course teaching history.
Filled database with papers, and modified the paper and author
models to make more sense.
Updated models again. Here is a changelist:
Paper: publication_type is now fixed to a set of choices.
CourseInstance: role is now fixed to a set of choices

Papers and teaching now populate with stored papers and course
instances from the database.

Views has several helper functions added, and the key view functions
have been modified to show papers and teaching. In particular:

format_authors: Given a paper, return a formatted string of authors
	sorted by last name.

get_item: A new registered filter for templates that allows you
	to use dictionaries like normal (I don't know why this
	isn't added by default)

semester_compare: Given two strings of the form
	"[Winter, Spring, Summer, Fall] [Year]"
	sort them in descending lexicographic order but
	keyed by YEAR FIRST.
Minor modifications of templates: added CV to index.html and some
links to base_academic.html
