Property Delegation Tools (#2)

The starter code defines a data class called Flag containing a Boolean called b with a default value of false. In main(), create three vars: d of type Double, s of type String and f of type Flag, all delegated to notNull(). For d and f, use explicit type declarations but for s use a type parameter for notNull().

Using capture from atomictest, try reading from d, s and f before they are initialized and validate the output using atomictest.eq. Then set d to 1.1, s to "yes" and f to Flag(true) and use eq to verify that they all take on the new values.
