Interface for data format conversion

[pfliu-nlp]

Purpose:

• we can provide some out-of-box functions so that users can use them to convert the system output’s format from A to B, where
  • A: could the format that users are familiar to
  • B: could the format that ExplainaBoard requires

Methodology: summarize potential scenarios

• tsv|conll -> json
• tsv|conll|json + additional information-> json_with_user_configs where json represents a json format without user specified information (e.g., metadata, features)

(feel free to add more situations)
