Implement users and login functionality

[StickyKeys]

• Add login view
• Add navigation bar to access logging in, logging out, and showing user who is logged in (Should the drop down have a settings view?)
• Write back end routines and routes to handle this request (Security decorator functions?)
• Use JWT cookies for this implementation
• Try referencing your document so you can add details to it to clarify the exact structure in the db and how you plan to implement this solution
