Allow multiple statements in single query

Alexander Mancevice · Alexander Mancevice · commit 743e4c961521 · 2016-02-04T15:39:38.000-05:00
Allows users to pass in multiple ;-separated queries into the same call.
Returns a list of ResultSet instances, as if the query() method had been
mapped across the different queries.

```python
client.query("SELECT * FROM mymeas WHERE time&gt;now()-1h; " \
    "SELECT * FROM othermeas WHERE time&gt;now-1h")
```
