List API (G1CMZ): List Processing API

[StephenG1CMZ]

Pier4r, thank you for your words of encouragement.

I admit it was disappointing when I discovered V1.2 had been released for some time without comment even though it would not compile ( the missing names were accessible in local backups, until I lost them).

But although the collection as a whole has attracted little interest yet, several of the included routines were the subject of threads enquiring how to implement tasks using PPL features, and those were always answered helpfully.

I also drew much inspiration from the list processing and puzzles threads (not aimed at the Prime), which led me to collect together several list procedures, and then compare them with list primitives from Wikipedia and Python to ensure some level of completeness and portability.

The next big task would be to add the many additional list primitives available in Java...
In the meantime, if there are any particular functions I've missed - suggestions are welcome.
