/**
 * Takes the UI model and process it and add the operations to the template.
 * Processing can be of two types EMF based or template based. Here this class
 * is EMF based. For an operation this class adds the input and output element
 * declarations as well. The new elements would be inheriting from the base type
 * mentioned in the "service_conf.properties", Any issues with the properties
 * file, the operation names, the parameter names all affect this class's
 * execution. Fits into the processor chain of template processing.
