This builder creates a composite test suite, containing a separate test suite for each present in the features specified by FeatureSpecificTestSuiteBuilder.withFeatures([]).

<B> The concrete type of this builder (the 'self-type'). All the Builder methods of this class (such as FeatureSpecificTestSuiteBuilder.named(java.lang.String)) return this type, so that Builder methods of more derived classes can be chained onto them without casting.
<G> The type of the generator to be passed to testers in the generated test suite. An instance of G should somehow provide an instance of the class under test, plus any other information required to parameterize the test.
