[GitHub] lucenenet pull request #212: LUCENENET-469 - enumerables

GitHub user AndyPook opened a pull request:

    LUCENENET-469 - enumerables

    See https://issues.apache.org/jira/projects/LUCENENET/issues/LUCENENET-469 for background.
    
    This is an early stage proposal for implementing IEnumerable<T> on various "Enum" types. To enable `foreach` and linq style operators.
    
    This prototype provides `EnumEnumerator<T>` as a helper. It can be used in various ways to make the implementation of `IEnumerable<T>` more straightforward.
    
    I have modified `IBytesRefIterator` and `TermsEnum` to add `IEnumerable<BytesRef>` and therefore to all of it's descendants.
    
    The test (such as it is) demonstrates retrieving a `TermsEnum` from a reader. Then using `foreach` and a simple `.Count()` linq operator.
    
    If this approach is acceptable it ought to be adaptable to other Enum types
