Data Exporter extension for i2b2

i2b2 can now export patient data for a patient set. The workflow involves breakdowns in the webclient, which allow users to request exports and data managers to generate exports. The export types and options are fully configurable in the database. Detailed documentation on set up can be found here: Data Exporter Set-up

The below steps describe the overall process:

User logs into i2b2 webclient and runs a regular i2b2 query, checking the desired Data request breakdown option when running the query.
E-mail is sent to the data manager and the User, informing them that the user's data request has been made.
The manager logs in and reruns the user query with the Data Export breakdown selection to generate the export flat files.
The generated export flat file is stored in a configurable location on the i2b2 server.
An e-mail is sent to the manager confirming the file extract and how to access the files (which can be shared with the requester).

Notes for Developers

For Java 11 install, if you change the xsd (REST API message definitions), then you will need to regenerate gensrc via JAXB in Java 8. In the i2b2-core cell directory for which you're regenerating the XSD-Java, run the ant target "jaxb_gen" on Java 8 and then build as usual using Java 11.
