Looks like we don't expose the `Dataset` class as datastore.Dataset?

[jgeewax]

There are some docs that use the following syntax:

>>> from gcloud import datastore
>>> dataset = datastore.get_dataset('dataset-id')

I'm not sure if this is accurate, but either way, if we're following the convention of datastore/init.py, this should be:

>>> from gcloud import datastore
>>> dataset = datastore.Dataset('dataset-id')

However I don't see the import in __init__.py, so I'm guessing that neither of these work...?

Yeah get_dataset doesn't exist, I'm on it.

I did a git blame and that text was added in #509, a looooong time ago.

@jgeewax It turns out that dead code wasn't being used in the snippet anyhow, so it just gets axed in #715
