Hi @andygrove, after this change, the datafusion functions submodule seems
not included in PyBallista.
If I try to find `functions` within PyBallista
```
from pyballista import SessionContext, functions as f
filename = "sample.parquet"
ctx = SessionContext("localhost", 50050)
df = ctx.read_parquet(path=filename)
uri = df.select(f.col("stream_id"))
df.limit(10).show()
```
I'm getting the following error:
```
ImportError: cannot import name 'functions' from 'pyballista'
(/Users/.../datafusion-ballista/python/pyballista/__init__.py)
```
Or if I change my imports to:
```
from pyballista import SessionContext
from datafusion import functions as f
```
Then it says:
```
File "examples/test.py", line 11, in <module>
uri = df.select(f.col("stream_id"))
TypeError: argument 'args': 'Expr' object cannot be converted to 'Expr'
```
