collection of garbage files in the repo to remove

[hkershaw-brown]

This is to collect a list of files in the repo that are relics from pervious websites, aborted auto documentation creation, and who knows what else.

Note, this is just files that are not used at all. It is not a list of documentation that needs reordering.
