UPDATE: Developer can now define standard step as generator (with parameters in workflow file) using the @Generator annotation. This step will be executed before the "First" step as other generators.
FIX: In the workflow file, all the steps after a step that had no output now depend on the step. Before, there was only a dependency on the next step.
UPDATE: Add a new parameter "use.expression.step.parameters" in starindexgenerator step that reuse parameter defined in the expresion step.
DOC: Update steps.html page.
