Collecting errors when a workflow fails

[#1]

The catches="complete" option on a workflow step guarantees that the step will run if we hit any runtime errors during workflow execution.

The step below called "StepToCreateError" will generate an error at runtime.

In the catches step named "Finalize", we will print out any errors that occurred in the workflow messages.
