Sort Lists API: A collection of sort functions

[StephenG1CMZ]

I have discovered that some of these are not working... Either failing at run-time, or older versions failing to compile.
Where I have had this happen before with code that used to work for me, it has sometimes been caused by a dependence in the published version on some functions present in a backup copy (which the Prime implicitly calls if the version in the latest version is renamed or out of scope), after that backup is deleted.
