Arguments:

`In`	- A filename. Can also be an abstract name, which is subject to `library(prolog_source)` abstract file handling. See prolog_open_source/2. Note that this cannot be a stream as we need to read the file three times: (1) xref, (2) assign colours and (3) generate HTML.
`Out`	- Term `stream(Stream)` or filename specification
