## Summary:
genqlient has some code (`imports.go`) dedicated to tracking which
imports we need and avoiding conflicts, as well as converting a
(restricted) Go expression like `map[string]github.com/me/mypkg.MyType`
to an import (`github.com/me/mypkg`) and a type-reference
(`map[string]mypkg.MyType`) to be used in the context of that import,
and at least making some attempt to track conflicts. (Right now the
conflict-avoidance is not very smart, and not very well tested, but it
comes up rarely anyway.) Sadly, that code was a bit cumbersome to use,
because you had to first register the imports (typically from
`convert.go`), then use them (often from the template).
In this commit I refactor the order we write things in order to allow a
significant simplification of how we import; in particular we no longer
have to guess in advance what imports which template will need; it can
just do `{{ref <expr>}}` as before, and it just works. To do this, I:
- changed the importer to have only one API, which adds the import if
needed, and returns the reference either way
- added a check that we don't add imports after they're written
- reorganized the toplevel templates a bit to make sure that check never
fires; we now generate all the types and operations, then write the
imports and glue it all together
This removes a bunch of silly code, and should simplify the process of
adding custom (un)marshalers (#38).
While I was at it, I put the documentation of what expressions we
support in a more visible place, and added a type-assertion that your
custom context type implements context.Context (if applicable).
