docs(WIP_tools): add repoCmdFiles README and structure

[neiljthomson]

Best Practice for "Work In Progress" WIP is to create a separate image of the repo folder structure which is not directly involved with committing changes to the repo. The idea is work on files the WIP folder space until ready for merge/commit/push, then copy/paste to the matching folder/file in the repo (non-WIP) folders and then do a commit.

To support this a number of command (.bat) files are included to manage the WIP -> repo file transfer and a facility to make snapshots of the repo folder structure which can be for various reasons, including when needing to revert to a previous version of a file
