Source components are input data connectors for SQL/CSV/JSON; they can be used with SourceReader class or directly with PivotData.ProcessData.
GroupedSourceReader is used when PivotData should be loaded with already aggregated data (for example, result of SQL GROUP BY query).
CubeFileReader loads serialized data cube from file.
