 *
 * const app = muster({
 *   one: '1',
 *   two: 2,
 *   threeAndAHalf: '3.5'

 * const two = await app.resolve(parseFloat(ref('two')));
 * // two === 2
 *
 * const three = await app.resolve(parseFloat(ref('threeAndAHalf')));

 * This example shows how to use the [[parseFloat]] to convert a value of a [[value]]
