Validate form of email field

As a librarian, I want the email field to check for forms (@ followed by text and a dot) that indicate the address is properly formed.

1. Scenario
   Given the field = email
   when data is entered
   Then the field will verify that it includes text@text.text
2. Scenario
   Given the data entered in the field does not meet the verification criteria
   when entered
   then display a red small test message: Email address not formed correctly.
