What are "filemaps"?

[alexreg]

They're mentioned on https://rust-lang-nursery.github.io/rustc-guide/the-parser.html, but not defined. I think it would be good to explain what they are first.

Any updates?

Sorry @mark-i-m, I've had a lot on my plate and didn't get around to this. Over the weekend I was wanting to play around with rustc internals to create a tool similar to cbindgen so I imagine that'll give me a chance to document things and add a paragraph or two on filemaps/codemaps.
