Commas not ignored #16
Description
The dot language specification says that ; and , are ignored.

Semicolons and commas aid readability but are not required. Also, any amount of whitespace may be inserted between terminals.
I have a dot file that is rejected by DotParser because it has commas; it is accepted by the dot program. If I remove the commas the file is accepted by both. File attached.
