doing isinstance(obj, Sequence) makes calls with keys of dict impossible
Example:
Returns
```
d = {'a':'a', 'b':'b'}
table.upsert(values, d.keys())
```
`dict_keys(['a', 'b'])` is not of instance Sequence, but Iterable, therefore `ensure_tuple(dict_keys(['a', 'b']))` returns (dict_keys(['a', 'b']),)
which leads to invalid iteration.
dataset: databases for lazy people
In short, dataset makes reading and writing data in databases as simple as reading and writing JSON files.
To install dataset, fetch it with pip:
$ pip install dataset
Note: as of version 1.0, dataset is split into two packages, with the data export features now extracted into a stand-alone package, datafreeze. See the relevant repository here.
