Sign Up page

[michho8]

Sign Up Page:

• four fields for input: username, email, password, and double-check password
• add empty validation by setting states, errors appear when first loading too (would need to use listener)
  • checking at each text field for their error message, will show errors initially
• add password validation by comparing both password fields, must be the same TODO:
• [x] route the "Sign Up" button to the home page or to the profile page?
• [ ] use Listener or another way to only check the fields when the user presses the "Sign Up" button, complete this in Milestone 2 (adding proper functionality)
