Enhancement Description

The datacompy package compares dataframes. Here are features that would allow it to present it's report with buckaroo.

Datacompy has a report function that displays information about metadata differences between dataframes (column names in common, match percentage), and data level differences (actual rows in common, actual rows that are different).

The reports are limited to textual display. Buckaroo provides the core of a system that can do a better job of displaying this.

Summary stats are a good fit for the metadata differences. The inline differences fit with the base buckaroo usecase

Pseudo Code Implementation

Users should be able to run DatacompyBuckaroo(df1, df2, join='col_to_join') and be presented the UI
