Visits the nest host class of the class. A nest is a set of classes of the same package that
share access to their private members. One of these classes, called the host, lists the other
members of the nest, which in turn should link to the host of their nest. This method must be
called only once and only if the visited class is a non-host member of a nest. A class is
implicitly its own nest, so it's invalid to call this method with the visited class name as
argument.

@param nestHost the internal name of the host class of the nest.
