 *
 *
 * @example **Convert string to start case**
 * ```js
 * import muster, { startCase } from '@dws/muster';
 *
 * const app = muster({});
 *
 * await app.resolve(startCase('Hello World'));
 * // === 'Hello World'
 *
 * await app.resolve(startCase('hello world'));
 * // === 'Hello World'
 *
 * await app.resolve(startCase('HELLO world'));
