v2.1.0

• added fieldDef to the resolver context which points to the fields definition. This makes reading custom metadata set on the field for things like plugins easier.
• Modified middleware resolver to bypass middleware for things like type resolvers
• added eslint and linted all code in /src
• added eventing in the factory and definition to forward up logs that can be passed to a logger like bunyan
  • additionally, any logs with an error level will throw an exception during the make process (by design)
• added a validation check to the definition after compile which emits an error to the factory instead of the previous behavior where it would log to the console.
• updated build scripts to use latest version of rollup and babel-env preset
• added a log method to the definition which forwards up to the factory
• fixed a middleware bug where failed middleware would still execute the resolver function instead of immediately failing the request.
• added the graphql-factory-types plugin as part of the library. it can be added with the string literal types in the plugins array of the make method.
  • this will be the same for any included plugins shipped in the future
