A simple `types.gql` to define basic content types...
```graphql
type Post @options("where", "limit", "order") {
  title: String!
  content: String
}
```

The resulting schema...
```graphql
type Post {
  id: ID!
  title: String!
  content: String
}

type Posts {
  posts: [Post],
  count: Int
}

input postInput {
  title: String!
  content: String
}

type Query {
  post(id: ID!): Post
  posts(where: {}, order: {}, limit: {}): Posts
}

type Mutation {
  createPost(post: postInput): Post
  deletePost(postId: ID!): Post
  updatePost(postId: ID!, postInput): Post
}
```
