Prototype

[joj0s]

This PR includes the first prototype of the app, featuring the first implementation of the data model, as well as a table showing all the inserted data, and a page for each trait showing its details. Closes #3, closes #4 .

I'd like to draw the attention to the data model file (traitcuration/traits/models.py). In particular these points:

• The on_delete behaviour of the different models and whether they can ever be deleted or not. Right now I am treating them as such:
  • In the trait model, if its current mapping is deleted I am setting it to null. If we want to never delete a mapping from the database, the other option would be to protect it from being deleted
  • I am protecting traits as well as ontology terms being deleted
  • With the current implementation, users can be deleted, and when they are, their reviews and comments are set to a null owner
• Also regarding the user model. I have created a new one, however Django already has a built in user model for authentication. I suggest we use the custom one for testing, and when we implement actual authentication we could see if it is more convenient. Let me know if you agree
• I would also appreciate if you could check the individual fields in the model file and see if any field that should be nullable isn't, and vice versa. (In Django, null means it can be empty in the database, and blank means that that field can be left empty when filling in Django forms. )

I pushed a commit addressing all your comments besides the ones open for discussion. In particular:

• Added loading for UIKit via CDN
• Turned the status fields into enum (discussion on their computing is pending)
• Removed double blank line from settings.py
• Made the code in models.py, line 6, single line

I also added the model for reviews, which I accidentally left off of the previous commits
