## API usage

```
import datetime
import elicznik

with elicznik.ELicznik("freddy@example.com", "secretpassword") as m:
    # date range
    print("July 2021")

    readings = m.get_readings(datetime.date(2021, 7, 1), datetime.date(2021, 7, 31))

    for timestamp, consumed, produced in readings:
        print(timestamp, consumed, produced)

    # single day
    print("Yesterday")

    yesterday = datetime.date.today() - datetime.timedelta(days=1)
    readings = m.get_readings(yesterday)

    for timestamp, consumed, produced in readings:
        print(timestamp, consumed, produced)
```


## TODO & bugs

* Add support for accounts with multiple meters
* Convert the dates to UTC and handle switches from and to DST properly
* Make the dependency on tabulate optional
