( Parent ticket: #41 )

• No one else should have access. (customers should not have access to add/edit/remove products)
• Customers should not be able to view other customer information

All users (customer & admin will have access to below route:
/website/user/dashboard

• when component mounts, fetch user
  • user will have userType of customer or admin
  • check if user is an Admin. if yes, render one extra button/icon
    - when clicked on, it will Link to route specifically for admin-functionality (ie /website/manage)
