> 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.
