/**
 * Object Type Definition
 *
 * Almost all of the GraphQL types you define will be object types. Object types
 * have a name, but most importantly describe their fields.
 *
 * Example:
 *
 *     $AddressType = newObjectType([
 *       'name'   => 'Address',
 *       'fields' => [
 *         'street'    => ['type' => stringType()],
 *         'number'    => ['type' => intType()],
 *         'formatted' => [
 *           'type'    => stringType(),
 *           'resolve' => function ($obj) {
 *             return $obj->number . ' ' . $obj->street
 *           }
 *         ]
 *       ]
 *     ]);
 *
 * When two types need to refer to each other, or a type needs to refer to
 * itself in a field, you can use a function expression (aka a closure or a
 * thunk) to supply the fields lazily.
 *
 * Example:
 *
 *     $PersonType = newObjectType([
 *       'name' => 'Person',
 *       'fields' => function () {
 *         return [
 *           'name'       => ['type' => stringType()],
 *           'bestFriend' => ['type' => $PersonType],
 *         ];
 *       }
 *     ]);
