Summarize directory groups with an action

Set submit_whole=true to ensure that an action is always submitted on the whole group of included directories. For example, you could use this in an analysis action that averages over replicates. Say your directories have values like

{
  "temperature": 1.0,
  "pressure": 0.3,
  "replicate": 2
}

with many directories at the same temperature and pressure and different values of replicate. You could average over all replicates at the same temperature and pressure with an action like this:

[[action]]
name = "average"
[action.group]
sort_by = ["/temperature", "/pressure"]
split_by_sort_key = true
submit_whole = true

Actions that summarize output have no clear location to place output files (such as plots). Many users will write summary output to the project root and omit products. In this way, you can rerun the analysis whenever needed as row will never consider the action complete.
