Parser fails if .dot file has comments

[Podbrushkin]

If .dot file contains commented-out lines with #, it cannot be parsed, exception is being thrown:

Single-line comments # and block comments /* blabla */ are legal syntax of .dot files. I think library shouldn't fail when they are presented in provided file.

This is how I've used it:

private void parseDot(String dot, File dotDir) {
        try {
            // Graphviz.useEngine(new GraphvizCmdLineEngine());
            Graphviz.useEngine(new GraphvizV8Engine(), new GraphvizJdkEngine());
            MutableGraph g;
            g = new Parser().read(dot);
