> ModelDataConverter is an interface that defines methods for converting a
> generic model data object to a collection of rows and the other way around.
> It is used when we are exporting the model data to a table, as well as
> loading model data from a table for inference.
> * Add ModelDataConverter which defines the model data conversion methods.
> * Add SimpleModelDataConverter which is a specific model data converter
> where the model data is represented as meta data and a collection of strings.
> * Add LabeledModelDataConverter which is a specific model data converter
> where the model data is represented as meta data, a collection of strings,
> and a collection of label values.
> * Add RichModelDataConverter which is a specific model data converter where
> the model data is represented as meta data, a collection of strings, and a
> collection of auxiliary rows.
> * Add ModelConverterUtils which provides utility functions for implementing
> the above model data converters.
