URL: https://github.com/apache/datafusion-python/pull/839
# Which issue does this PR close?
Closes #713
Closes #807
Closes #810
Also no issue assigned but fixes a bug in `functions.array()`
# Rationale for this change
These are a handful of usability improvements.
# What changes are included in this PR?
- Adds `_repr_html_` to get a nice output in notebooks
- Allows for using `[]` to access array elements in an expression. If column
`a` is a list of integers you could do `col(a)[0]` to get the first element in
the list.
- Fixes an error in `array` so it operates correctly.
- Adds `DataFrame.transform()` which makes chaining dataframe operations
easier.

# Are there any user-facing changes?
No API changes, but the above all enhance usability.
