Merge pull request #1 from luksrn/master

From #Luksrn: Development of the list of items available in future search (functionality not yet developed). The design was changed to allow an entry point for the activity to be developed by each team. The next step is to create an option to see a list of articles already downloaded and also the access menu.
Adding the feature "Evaluation" to the PubShare application. This
feature provides a way for evaluating the articles that have been
downloaded and presents the evaluations already done by others
reviewers.
