Changes to log an entry

All tests pass.

Now, the home page is (changed to) home#index.

Made /entries/new look somewhat like <Screen Shot 2013-02-01 at 2.58.46 PM.png>.

Did it, per your request, using only Bootstrap Markup and simple_form, and without making any CSS changes.

The input at bottom, Categorize (which defaults to 'Family'), lacks its drop box icon.

I assume that's okay for now, since we don't have the tag system yet.
