## Summary:
In this commit I reorganize much of our documentation into a new `docs`
directory, where there will hopefully be more room to grow and to
organize things in a user-friendly way. There's almost no net-new
documentation, although of course it's a great time to review it anyway.
In particular:
- I moved the documentation for the `genqlient.yaml` config file into an
example file instead of GoDoc (which now just points to the example
file); I think this will be a lot clearer for casual users.
- I moved the documentation for the `@genqlient` directive out of GoDoc
and into a GraphQL schema file (since while it's a comment it's all
real syntax), likewise, and made the `GenqlientDirective` type private
(since there's now nothing useful to do with it).
- I moved `DESIGN.md` and the logo into `docs/` (just to keep the
toplevel a bit cleaner), and separated the Contributing section of the
README into `docs/CONTRIBUTING.md` (which github will automatically
link on various issue and PR pages).
This leaves it so that:
- README.md is the only documentation at the toplevel (and will become
just the high-level introduction as I add more user docs to `docs/`)
- GoDoc is only documentation for if you want to call genqlient
programmatically (which is fairly limited as the API surface is quite
small: it's now just Main, Generate, and Config, plus a constructor, a
single method, and a bunch of fields on the latter)
In future commits, I'll add some more new documentation to the `docs`
directory.

## Summary:
In this commit I add support for inline fragments
(`... on MyType { fields }`) to genqlient. This will make interfaces a
lot more useful! In future commits I'll add named fragments, for which
we'll generate slightly different types, as discussed in DESIGN.md.
In general, implementing the flattening approach described in DESIGN.md
was... surprisingly easy. All we have to do is recurse on applicable
fragments when generating our selection-set. The refactor to
selection-set handling this encouraged was, I think, quite beneficial.
It did reveal two tricky pre-existing issues.
One issue is that GraphQL allows for duplicate selections, as long as
they match. (In practice, this is only useful in the context of
fragments, although GraphQL allows it even without.) I decided to handle
the simple case (duplicate leaf fields; we just deduplicate) but leave
to the future the complex cases where we need to merge different
sub-selections (now #64). For now we just forbid that; we can see how
much it comes up.
The other issue is that we are generating type-names incorrectly for
interface types; I had intended to do `MyInterfaceMyFieldMyType` for
shared fields and `MyImplMyFieldMyType` for non-shared ones, but instead
I did `MyFieldMyType`, which is inconsistent already and can result in
conflicts in the presence of fragments. I'm going to fix this in a
separate commit, though, because it's going to require some refactoring
and is irrelevant to the main logic of this commit; I left some TODOs in
the tests related to this.
