Parameters:
- `fn` : string: the (relative or absolute) filename of the .html, .js

path and an any extension. The latter is dropped and not used.
- `createdby`: int: width in pixels of the 'Created by pyFormex' logo
appearing on the page. If < 0, the logo is displayed at its natural
width. If 0, the logo is suppressed.
- `**kargs`: any other keyword parameteris passed to the

is derived from the `fn` parameter.
Returns the absolute pathname of the generated .html file.
