> Parquet is a columnar storage format developed by Twitter. Implement Parquet
> (http://parquet.io/) support for Tajo.
> The implementation consists of the following:
> * {{ParquetScanner}} and {{ParquetAppender}} - FileScanner and FileAppenders
> for reading and writing Parquet.
> * {{TajoParquetReader}} and {{TajoParquetWriter}} - Top-level reader and
> writer for serializing/deserializing to Tajo Tuples.
> * {{TajoReadSupport}} and {{TajoWriteSupport}} - Abstractions to perform
> conversion between Parquet and Tajo records.
> * {{TajoRecordMaterializer}} - Materializes Tajo Tuples from Parquet's
> internal representation.
> * {{TajoRecordConverter}} - Used by {{TajoRecordMateriailzer}} to
> materialize a Tajo Tuple.
> * {{TajoSchemaConverter}} - Converts between Tajo and Parquet schemas.
