Individual Events

1. Only allow unique accounts to be associated with an event.
 2. When an account is associated with an event, if a user logs in that is not an admin user. the user should see the event details, that is associated with their account. 

In second task, db query is fetching all the events due to pagefind used. Its working fine without pagefind.
