JSON to CSV conversion operator

The JSON-to-CSV conversion operator was implemented to solve a common problem when exporting JSON document content into a Hadoop layer which expects TSV format.

To circumvent the implementation of a dedicated converter for each JSON structure, the operator requests a list of content references pointing towards the fields inside a JSON document that must be included inside the export.

For each incoming JSON object the operator reads the referenced content and exports it in the same order into a character separated string.
