 * A single-value metrics aggregation that keeps track and returns the
 * maximum value among the numeric values extracted from the aggregated
 * documents. These values can be extracted either from specific numeric fields
 * in the documents, or be generated by a provided script.

 *
 * Aggregation that keeps track and returns the maximum value among the
 * numeric values extracted from the aggregated documents.
 *
 * @example
 * const agg = esb.maxAggregation('max_price', 'price');
 *
 * @example
 * // Use a file script
 * const agg = esb.maxAggregation('max_price').script(
 *     esb.script('file', 'my_script').params({ field: 'price' })
 * );
 *
 * @example
 * // Value script to apply the conversion rate to every value
 * // before it is aggregated
 * const agg = esb.maxAggregation('max_price').script(
 *     esb.script('inline', '_value * params.conversion_rate').params({
 *         conversion_rate: 1.2
 *     })
 * );
 *
 * @param {string} name The name which will be used to refer to this aggregation.
 * @param {string=} field The field to aggregate on
