/**
 * Runs the `tasks` array of functions in series, each passing their results to
 * the next in the array. However, if any of the `tasks` pass an error to their
 * own callback, the next function is not executed, and the main `callback` is
 * immediately called with the error.
 *
 * @name waterfall
 * @static
 * @memberOf module:ControlFlow
 * @method
 * @category Control Flow
 * @param {Array} tasks - An array of [async functions]{@link AsyncFunction}
 * to run.
 * Each function should complete with any number of `result` values.
 * The `result` values will be passed as arguments, in order, to the next task.
 * @param {Function} [callback] - An optional callback to run once all the
 * functions have completed. This will be passed the results of the last task's
 * callback. Invoked with (err, [results]).
 * @returns undefined
 * @example
 *
 * async.waterfall([
 *     function(callback) {
 *         callback(null, 'one', 'two');
 *     },
 *     function(arg1, arg2, callback) {
 *         // arg1 now equals 'one' and arg2 now equals 'two'
 *         callback(null, 'three');
 *     },
 *     function(arg1, callback) {
 *         // arg1 now equals 'three'
 *         callback(null, 'done');
 *     }
 * ], function (err, result) {
 *     // result now equals 'done'
 * });
 *
 * // Or, with named functions:
 * async.waterfall([
 *     myFirstFunction,
 *     mySecondFunction,
 *     myLastFunction,
 * ], function (err, result) {
 *     // result now equals 'done'
 * });
 * function myFirstFunction(callback) {
 *     callback(null, 'one', 'two');
 * }
 * function mySecondFunction(arg1, arg2, callback) {
 *     // arg1 now equals 'one' and arg2 now equals 'two'
 *     callback(null, 'three');
 * }
 * function myLastFunction(arg1, callback) {
 *     // arg1 now equals 'three'
 *     callback(null, 'done');
