Five steps

Step 3 always seemed like it was doing too much, both setting the resources AND submitting the job. I propose we split it in two, with step 3 setting the resources (it gets its own confirm button), and step 4 submitting the job, optionally setting the label and description.


So basically:

1. Choose a structure
2. Configure the calculation parameters
3. Select the resources
4. Submit the workflow
5. Monitor and view results
