HI Cyrille and others.

I modified the abstraction to make opening the two files easier. It
uses file/parentfolder from the PdMtlAbstractions. (try it !! It
answers your question)

For the C programming and such, I just meant that it is nice if we can
tend to make Pd easier to use for people that are not that much used
to advanced programming. A good documentation and a nice structure
helps a lot...
