Implement Login Screen

[JackTheVac]

A rough layout of login screen

• Add text input field that takes in user email
• Add text input field that takes in user password (maybe mask the password as they type in)
• Add a button that says "Log In", and don't worry about the function to authenticate just yet
• Add a button that says "Don't have an account yet, sign up here", and don't worry about the function yet

text input documentation and how to record down the user input using useState Variables

For text input example that react native give, when you get to

`const UselessTextInput = () => {
  const [text, onChangeText] = React.useState("Useless Text");
  const [number, onChangeNumber] = React.useState(null);

  return (
    <SafeAreaView>
      <TextInput...
.....

`

Try not to use React.useState. Import the module (look at useState Variable documentation on how to do that) and call the useState function directly
