Give user the ability to export AQL and run as a script - automate execution

[zeusorionIBM]

Description:
The Elyra Visual Editor for NLP Rules give users the ability to interactively build NLP expressions and test them against a document and view results. Once the user is satisfied with the rules and results, the user should have the ability to get the AQL files to execute against a set of documents and automate the execution if the user wishes.

• The current implementation would change on the backend to return the AQL text to the NLP Visual Editor and give the user the ability to export the AQL files.
• If there are special commands to execute, the user would have to be provided with them to improve usability.
