A react wrapper around auth0 js so that we can use custom screens.

#Refer to these documents :

1. https://auth0.com/docs/libraries/auth0js
2. https://auth0.github.io/auth0.js/

Things we did :

1. isLoading : A loding state which becomes true untill things are resolved.
2. isAuthenticated : A state which determine if the user is authenticated.
3. user : The user state which contains the user details.
4. error : The error state for finding the issue.
5. getAccessToken : To retreive the access token of the logged in user
6. signup : A function used for signing up new users.
7. login : A function for logging in existing users.
8. logout : A function for loggin out users.
9. Auth0Provider : A provider where developers should add the config for webAuth initialization
10. withAuthenticationRequired : A higher order component used to wrap component to only allow access to logged in users.

Need to do :

1. Error Handling
2. Email already exists
3. Faster Respose time (Loading should be decreased)
