Decisions

1. Lab rating will be a rating of any lab page or the user’s rating of all the experiments. Does not matter, we will just display the value that GA gives us. Lab ratings like the experiments will be also displayed in line with the breadcrumb.
2. We will be displaying the experiment rating only on the exp pages and not the individual page ratings. However the rating
   can be done on any exp page.
3. The components will be called rating-submit and rating-display.

To Do

1. Lab Rating to be displayed. Collect it from Google Analytics on the spreadsheet and then display it.
2. Experiment Rating is to be displayed on the list of experiments alongside the lab page of the list of experiments.
3. Exp Rating to be displayed in line with the breadcrumb
4. Rate Me ( Button to rate the page/exp/lab) will be present in the header.
5. Documentation of the Rating Feature
