[Markdown] How to embed PlantUML

1. Process File

        throws IOException, InterruptedException {

    final Option option = new Option(); 
    if (inFile.exists() == false) {
            throw new IllegalArgumentException();
    }
    FileSystem.getInstance().setCurrentDir(inFile.getAbsoluteFile().getParentFile());
    BlockUmlBuilder builder = new BlockUmlBuilder(
            new ArrayList<String>(), //option.getConfig(),  
            "UTF-8", //option.getCharset(), 
            createEmpty(), //option.getDefaultDefines(file), 
            new InputStreamReader(new FileInputStream(inFile), "UTF-8"),
            inFile.getAbsoluteFile().getParentFile(), 
            inFile.getName());      

    //final List<GeneratedImage> result = new ArrayList<>();
    int count = 0;
    for (BlockUml blockUml : builder.getBlockUmls()) {    
        final Diagram system;
        try {
            system = blockUml.getDiagram();
            final List<FileImageData> exportDiagrams = PSystemUtils.exportDiagrams(system, 
                SuggestedFile.fromOutputFile(new File(outDir, outFilePrefix  + count) , outFormat, 0),
                new FileFormatOption(outFormat),
                false);
            if (exportDiagrams.size() > 1) {
                    exportDiagrams.size();
            }    
            count++;
