Predict

``` python
from jeffy.engine import Engine
engine = Engine()
engine.load()

result = engine.predict(
    "banking77",
    "I was charged twice for the same transaction"
)
# {"label": "transaction_charged_twice", "confidence": 0.999}
```

Train your own

``` python
from jeffy.train import train_classifier
clf = train_classifier(
    texts=["great product!", "terrible", ...],
    labels=["positive", "negative", ...],
    task_id="my_reviews",
)

clf.predict("exceeded expectations")
# {"label": "positive", "confidence": 0.87}
```
