Add sign-in, sign-out, and sign-up

User must confirm password upon sign-up. Password must be longer than 8 character. If password is forgotten, an email will be sent to reset the password.
Move 'devise/shared/links' partial out of form_for
Start styling header for app
Add code to create a customizable header
Delete unnecessary files
Add class ids to sign-in and sign-up
Add functionality to sign-in and sign-up buttons in nav bar

On the landing page, a user can click on the sign in button if he or she has an account.
If the user does not have an account, the user can click on the sign-up button.
The buttons will take the user to the correct corresponding pages, where the data they enter persists into the database.
Add styling to homepage.

The nav bar is mostly functional with the exception that once users enter their credential for sign-up, they are not being redirected.
In addition, the forgot password email function needs to be tweaked.

I am moving away from this aspect of the application to focus more on functionality and to implement desired features.
Remove styling

Styling was removed in order to focus on creating features. At the moment, there are some functionality issues with sign-in and forgotten password. They are currently being sorted out.
Add 'Edit Account' link to home page

A signed in user can now edit and delete his or her account
