Make single DeclareIO call mandatory
Created by: williamfgc
InquireIO will return nullptr if DeclareIO not called. Prevents conflict with xml parsing and creating IOs.
During the maintenance period on Monday, 14 Oct 2024, all new projects will no longer create a container registry as part of the project area. Already existing projects will be unaffected at this time. Instead, users should utilize the official ORNL container registries at camden.ornl.gov (internal/moderate) and savannah.ornl.gov (external/low). Please see ORNL Today article for more info.
