How can I add or remove fields from MongoDB?

Assuming that you have updated the database itself, you have to update two classes:

• Config.java that has the setters/getters of every single MongoDB field.
• MongoHandler.java that reads from the database.

How can I update the input arguments to support my new ED method?

You have to update the Console.java class and more specifically the setOptions() method. The tool utilizes the Apache Commons CLI library for console parsing, so all you have to do is to add your new arguments and the library will take care of the rest. As the existence of the arguments is checked once at the beginning of the EvS class, you have to create the appropriate public methods that will return the values to the EvS class during execution. Also, don't forget to update appropriately the relevant section of the config.properties file along with the Config class.
