log in as a user

As a parent I want to be able to login to my account so I can see my community page.

• The user must be able to see a profile logo in the header of each page.
• The user must be able to click the profile which will take them to a sign in form.
• The user must be able to view an option to create an account if they do not already have one.
• The user must be able to enter their username and password in the login form.
• The user must be alerted if there were any sign in issues.
