Design and Public API documentation completed.
The draw.io diagrams are in Gerrit. If the page is ever deleted, they will be lost. They ae now saved in XML format in gerrit. The design documentation links to the examples in github rather than quoting them in the document. General tidy up and cleaning of links, rewording, and reformatting of desgin document. Added missing diagram to the Design document. Updated and tidied up the internal PAP/PDP document. General improvement of documentation.
