v0.3.0

Breaking/New:

• isTypeOf is now called (if defined) to assert that GraphQL object types are executing against the correct values #38
• Field resolve functions now have a new API: resolve(value, args, info), where info is an object which contains the same information which used to be separate arguments, and includes more useful stuff! https://github.com/graphql/graphql-js/blob/master/src/type/definition.js#L359
• graphql() no longer formats its errors. result.errors is now a list of GraphQLError instances, which provides useful information including stack traces.
• Arguments and Input Object Fields not provided are not set on the internal JS objects. The previous behavior was to set null for these arguments and fields.
• Scalar definition coerce and coerceLiteral have been renamed to serialize and parseLiteral respectively.
• Scalar definitions may now define parseValue which is used when interpreting variable values of that type. Previously coerce was being reused for this purpose.

Fixed:

• Nested input objects are no longer excluded by introspection.
• Fix issue where a fragment spread with missing definition breaks the validator.
