Crate - Design by Introspection for D web APIs

[Sönke Ludwig]

Congrats, this looks like a nice and practical system, and the docs are 
also well written and structured¹!

Personally, I haven't had a lot to do in this area in recent years, so 
the unpublished things that I started long ago unfortunately haven't 
really progressed. This makes it especially nice to see something new in 
the D web realm!


¹ There should definitely be a link to them in README.md, though.
