[PATCH v2 3/6] views/xmlrpc: Add documentation for API methods

[Finucane, Stephen]

> This will be useful for populating the XML-RPC API documentation.
> 
> Note that this uses the Google-style docstring format. This format is
> easier to read than the information-dense, "classic" Sphinx docstring
> format making it more suitable for use with pydoc (which does not do
> any post-processing and it used by the 'DocXMLRPCServer' module). If
> generating documentation using Sphinx, this will require the usage of
> the 'sphinx.ext.napoleon' extension.
