Start adding support for html model (BROKEN)
Add html model - get tests passing in intermediate state
Make features use Token object instead of multiple arrays
Merge branch 'master' into html_model

Conflicts:
	lib/free_cite/crfparser.rb
Get training/testing model working again
Take junk out of tagged html references
Dumb HTML model
(Doesn't actually know anything about HTML)
Update gitignore
Add public interface for parsing html cites, plus basic test, and correct duplicate-tokens issue
Add separate template for HTML parsing which takes tags into account
Add more features and tweak training params with no substantial effect
Fix html template to actually use html tag name, tweak things
Give up on using parent tag name
Give up on using end of html node
Verify comments and empty tags stripped
