Module schema

Traits for describing a GraphQL schema in Rust.

The use_schema macro will mostly output types that make use of the traits in this module to describe the schema. The derives then combine these types with the QueryBuilder type to enforce the restrictions of the schema.

Note that this module is mostly concerned with the marker types output by use_schema, not the actual types users work with. The traits will usually be implemented on marker types, the geneirc parameters will usually be marker types and the associated types will also usually be markers.
