Generic type parameter not analyzed

[keith-turner]

The following Accumulo method was not detected by APILyzer. This is a method in the public API. Howerver the type IteratorScope is not in the public API. It was not detected because its a Type parameter.

  void attachIterator(String namespace, IteratorSetting setting, EnumSet<IteratorScope> scopes) throws AccumuloException, AccumuloSecurityException,
      NamespaceNotFoundException;

If possible, would need to check for complicated generics on methods and params like:

  <T extends Comparable<Set<String>>> T registerComparator(Class<T> c, Map<Name, Scopes<? extends ComparableScopes<?>>> s);

This issue should consider generics in exceptions also. See #5
