Task: bump version to v0.2
Task: dynamically sized query input box width

Instead of having a fixed width input box for entering the query text,
we have the box scale according to the screen size, like the rest of the
layout. [ci skip]
Task: conditional probability for single features

For some reason, when classifying a document that consists only of one
feature, the hierarchical classifier only labels the document as neutral
or positive, even when the confidence values are less than 0.5.

I'm still not sure why this is the case, however I am addressing the
issue for the part of the web interface that shows the influence of each
of the individual features that make up the query by just using the
conditional probability of the feature across the labels instead of
trying to classify it. In the mean time, this addresses issue gh-27.
Task: web UI feature influence use only unigrams

While higher order n-grams (bigrams) can have significant influence,
they are hard to visualize when mixed together with unigrams. By just
using unigrams, we can also unpack the feature from its tuple, further
reducing the visual complexity of the output by approximating normal
text.
Task: move conditional prob. code into function
Task: change neutral txt color from gray to black
Task: neutral text confidence for shade of gray

Have the neutral features appear darker the more confident we are in the
label.
Add date to query log
Add results of our system for SemEval-2013
Create corpus subpackage

It would be nice to have a place to organize all of the corpus functions
as we expand to additional datasets. Therefore, we are preparing by
creating a corpus subpackage and moving our current corpus tools.
Move SemEval experiments and use config file
Move Sander's Twitter Sentiment Corpus
Move the Stanford sentiment corpus (Sentiment140)
Move variables from constant module into config
Add: art-festival sentiment corpus
Transfer query width style to CSS from HTML
Placeholder text for query input on index page
Change HTML indent size to 2-spaces
Remove unneeded <br> tag
Use <div> and <p> instead of <br>
