Issue by skrawcz

Originally opened as stitchfix/hamilton#32

Goal of this PR is to provide more extensive examples.

Inspiration is from:
https://github.com/Netflix/metaflow/blob/master/metaflow/tutorials/01-playlist/playlist.py

Two interesting things to note here:

  1. We could have the driver do the loading of the CSV, or we could have a function to do it.
  2. Filter operations are easiest to happen in the driver I think. Not to say you can't do it,
    we'd just need better logic around creating the dataframe, and not trying to combine series
    with various index lengths. Hmm.

Fixes ray object dereferencing

Ray does not resolve nested arguments:
https://docs.ray.io/en/latest/ray-core/objects.html#passing-object-arguments

So one option is to make them all top level:

- one way to do that is to make the other arguments not clash with any
possible user parameters -- hence the `__` prefix. This is what I did.
- another way would be in the ray adapter, wrap the incoming function,
and explicitly do a ray.get() on any ray object references in the
kwargs arguments. i.e. keep the nested structure, but when the ray
task starts way for all inputs... not sure which is best, but this
now works correctly.
