Feature arglist option aliases
Allows migration of command-line options, with versioning to track the 'age' of the changes.
Eg, if -decomposeParDict gets changed to something like -decompose-dict, but we still wish to accept the older name for it:
argList::addOptionCompat("decompose-dict", { "decomposeParDict", 1612});
argList::addOptionCompat("no-function-objects", {"noFunctionObjects", 1612});This emits a warning about the option being out of date, but will rewrite it with the newer option name, which is what would be referenced internally.
