-## Subclassing `BasePlugin`
-
-To make life easier, there are several subclasses of `BasePlugin`
-under `countess.core.plugins` ... each of these provides common 
-features used in different types of plugins.
-
-### PandasSimplePlugin
-
-### PandasTransform**X**To**Y**Plugin
-
-There are several classes of the form `PandasTransform`**X**`To`**Y**`Plugin`.
-
-The most obviously useful ones are `PandasTransformSingleToSinglePlugin`, 
-which translates a single value into another single value, and 
-`PandasTransformDictToDictPlugin`, which translates an entire table row.
-
-To use these classes, subclass the appropriate one for your plugin and 
-override `process_value`, `process_row` or `process_dict` as appropriate.
