 * }
 * // Creates an instance of ExampleClass
 * static exampleInstance = ExampleClass.create({ property1: 'value', property2: 42 });
 * ```
 *
 * @param classType The class to instantiate and initialize.
 * @param options The configuration of the class, including which fields to omit
 * and which fields to make optional.
 * @returns A factory function that creates an instance of the class.
