Visits a member of the nest. 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 if
the visited class is the host of a nest. A nest host is implicitly a member of its own nest, so
it's invalid to call this method with the visited class name as argument.

@param nestMember the internal name of a nest member.
