ElementIDOutputAction

Action for copying extra element IDs into auxiliary variables for output.

This action is triggered when "output_extra_element_ids" is set to true. AuxVariables and AuxKernels relevant to the extra element ids defined on the mesh are automatically added to the problem, and the resulting element integers are also outputted to the Exodus file.
