Add option to projects to allow users to classify and extract at the same time

The current workflow is effective for crowdsourcing, but when projects are being used by an individual or a small group of people, It would make sense to have the option to combine information extraction and classification.

Tonight, I found myself classifying responses and then having to re-read the same ones almost immediately afterwards to extract the information I had just read. This felt like a duplication of effort, as I had to find the same information, in the same documents, twice in quick succession. It would have been better to have answered both the project questions and the classification question at the same time.

We could make the classification section in the sidebar use the same style as the one on embargoed requests to save space. The extraction boxes could go above or below it. This would allow users to extract information and classify responses at the same time, significantly reducing time and effort.
