Rewriting to use PlantUML

[SaKKo]

Hi, it seems like this repo is inactive for a long time now.
I forked and made some modification for so that this work with plantuml.
I'm still a beginner in sharing code but I think plantuml looks more friendly when generating ER diagram.

Not sure if there is a better way to share this.

Hi @SaKKo , railroady still works fine, though yeah there haven't been any new features in a while. Does your fork preserve the default .svg output, or is it only the plantuml files?

@preston if it "still works fine" why not merge some PRs with fixes like mine?
