List API (G1CMZ): List Processing API

[StephenG1CMZ]

Thanks for pointing out that difficulty John. I hadn't considered that.
There are certainly several functions I could remove - but there will inevitably be a large number that are needed.

Would it help if instead of prefixing the names with "List", some other prefix were used?
Like Z perhaps, thus placing it near the end of the catalogue (only 4 other names, plus some symbols), or Y (no other names in the catalogue)?
Or would it still be inconvenient there?
