When one sets the notation font to a non-existent value this would later result in a "font not found" error, which is rather inconvenient.
It would be better to let \useNotationFont look into the font directories and check if the font is present, and give a more meaningful warning when not (and resetting to default Emmentaler).
A similar thing is with stylesheets. choosing a name for which no style is present results in ugly file-not-found errors currently. Instead we should have a warning and a fallback.
