   //      fred.bloggs@somewhere.com
   //
   //   ((-\w+)|(\.\w+)|(\_\w+))*
   //      This is probably the most complex section of  the whole
   //      expression. All I am looking for here are zero or more
   //      'words' prefixed by either a minus (-), dot (.) or
   //      underscore (_) all of which are legal characters in email
   //      addresses.
   //
   //   \@
   //      The one and only @ symbol used in the address
   //
   // [A-Za-z0-9]
   //      Now, I want at least one character that matches this rule
   //      (i.e. any letter from A-Z, uppercase or lowercase or a number
   //      from 0-9)

   //      characters that match the rule above, prefixed with either a
   //      dot (.) or a minus (-). For example, this would match the
   //      .xyz portion of abc@uvw.xyx.com
   //
   // \.
   //      A dot (.)
   //
   // [A-Za-z]{2,5}
   //      This final section ensures that the TLD (top level domain)
   //      portion of the email address is at least 2 characters long
   //      (as in .uk or .to) and no longer than 5 characters (to allow
   //      for .firm and .store)
