This release makes it easier to build apps on top of buckaroo.
Post processing functions can now hide columns
CustomizableDataflow (which all widgets extend) gets a new parameter of `init_sd` which is an initial summary_dict. This makes it easier to hard code summary_dict values.
More resiliency around styling columns. Previously if calls to `style_column` failed, an error would be thrown and the column would be hidden or an error thrown, now a default obj displayer is used.
[Datacompy_app](https://github.com/capitalone/datacompy/issues/372) example built utilizing this new functionality. This app compares dataframes with the [datacompy](https://github.com/capitalone/datacompy) library
