This code wasn't supposed to the in the ``__init__.py``, but imported in the ``__init__.py``. We were thinking that you'd be adding a new ``skbio/parse/sequences/iterators.py`` and then adding this line to the ``__init__.py``:

```
from skbio.parse.sequences.iterators import SequenceIterator, FastqIterator, FastaIterator
```

(e.g., like we do for ``parse_fasta`` and ``parse_fastq`` above). 

Sorry for the confusion, we may have not described it correctly on the call.
