EmptyDenialProc =

Used as the default denial handler for Command instances. When the proc returns true, it allows the global default handler to also run. We want the empty handler to return true so that the default (if it exists) will run.

def extract_command(match)
  return unless match.is_a?(MatchData) && match.names.include?('command')
  match[:command].downcase
end

#extract_details(data, match) ⇒ Object

Authorization only works when we’ve been passed a data object with a user field and a match object that contains a command field.

Extract those items and return them in an array. If those items don’t exist in the form we expect, return nil in place of those objects.
