/**
 * Interface Type Definition
 *
 * When a field can return one of a heterogeneous set of types, a Interface type
 * is used to describe what types are possible, what fields are in common across
 * all types, as well as a function to determine which type is actually used
 * when the field is resolved.
 *
 * Example:
 *     $EntityType = GraphQLInterfaceType([
 *       'name' => 'Entity',
 *       'fields' => [
 *         'name' => ['type' => GraphQLString()]
 *       ]
 *     ]);
