Documentation

Class for types that can be sent with api-builder. Given a Builder, a Route, and an instance of Sendable, we should be able to construct a Request for the API's server. If we can't, send returns Nothing and APIT complains about being unable to send the given data.

By default, the '()' instance for Sendable moves the query parameters of the Route into the body of the POST request. Most APIs handle both, but some will complain if they aren't sent in the actual query. If you send PostQuery instead of '()', the query params won't move from the actual query string when constructing the request.
