ToDos:
- change copy commands to movefile commands (put into temp. sub directories where the input file is located). We need to copy files in this script because ODA File Converter will process whole dirs instead of single files only.DXF files can be really large, which slows the process)
- vpype will crash because inkscape(ObjectToPath) fails -> lines have missing style attribute?
