Welcome page documentation code example problem - remove_column() doesn't exist

[zbarry]

In:

df = (
    pd.DataFrame(...)
    .remove_column('column1')
    .dropna(subset=['column2', 'column3'])
    .rename_column('column2', 'unicorns')
    .rename_column('column3', 'dragons')
    .add_column('newcolumn', ['iterable', 'of', 'items'])
)

remove_column() is not [any longer?] a function. I guess this should be remove_columns(), instead. Note that the latter only takes list arguments apparently, instead of just a string in the case where you only want to remove one column. Might be useful to support both types of inputs.

Just found this old reference to the non-plural spelling as well in the api.html page -

df = pd.DataFrame(...).remove_column(cols=['col1', ['col2']])

(Just actually starting to look into how to use your package, haha).

These are good catches! Docs are one of the hardest things to maintain haha. I am thinking of moving over to doctests, so that example usage and their associated tests are automatically shown for each function.

Also: filter_on is called filter_column in the API page example.

Cool stuff, thanks for the catch, @zbarry. Would you be open to a documentation PR fix? The way to do so would be to first fork the repository, then create a branch off your fork, and PR into my master branch from your fork.
