fix link in readme
local_settings.rb should have been in .gitignore
Much faster arxiv importer

arxivsync import/update!
Fix some author handling, feed last_paper_dates
Add exception_notifier for email notifications
Threaded comments
Only show CURRENT_FEEDS on sidebar
Use comment.destroy to ensure counter_cache update
Importing now handles updates to existing papers
Error reporting outside of Rack framework
If paper import fails, continue but notify of error
Starting on Author model
Update schema.rb, structure.sql.

http://guides.rubyonrails.org/migrations.html#what-are-schema-files-for
Show subscribed feeds at top of sidebar
Simple landing page layout

time; I'm not sure how (if) it originally worked as expected.
Finally getting to the frontend search.
Authors can now be searched independently from paper contents
