Generator source code and XML comments

[mellinoe]

Hey @jwollen , first of all just wanted to say thanks for open-sourcing this. I'm trying to get into Vulkan and this looks like a well-designed wrapper from what (very) little I've managed to do so far 😄 .

I had a couple questions:

• Are you still planning on open-sourcing the generator code?
• Is it simple to add XML comments to the generated wrapper methods? I see that there are decent comments in the Vulkan XML spec that could probably be useful as a starting point. If the generator code was opened up I'd be willing to take a crack at adding this.
