/**
 * A dependency-injected version of the [async.auto]{@link module:ControlFlow.auto} function. Dependent
 * tasks are specified as parameters to the function, after the usual callback
 * parameter, with the parameter names matching the names of the tasks it
 * depends on. This can provide even more readable task graphs which can be
 * easier to maintain.
 *
 * If a final callback is specified, the task results are similarly injected,
 * specified as named parameters after the initial error parameter.
 *
 * The autoInject function is purely syntactic sugar and its semantics are
 * otherwise equivalent to [async.auto]{@link module:ControlFlow.auto}.
 *
 * @name autoInject
 * @static
 * @memberOf module:ControlFlow
 * @method
 * @see [async.auto]{@link module:ControlFlow.auto}
 * @category Control Flow
 * @param {Object} tasks - An object, each of whose properties is an {@link AsyncFunction} of
 * the form 'func([dependencies...], callback). The object's key of a property
 * serves as the name of the task defined by that property, i.e. can be used
 * when specifying requirements for other tasks.
 * * The `callback` parameter is a `callback(err, result)` which must be called
 *   when finished, passing an `error` (which can be `null`) and the result of
 *   the function's execution. The remaining parameters name other tasks on
 *   which the task is dependent, and the results from those tasks are the
 *   arguments of those parameters.
 * @param {Function} [callback] - An optional callback which is called when all
 * the tasks have been completed. It receives the `err` argument if any `tasks`
 * pass an error to their callback, and a `results` object with any completed
 * task results, similar to `auto`.
 * @returns {Promise} a promise, if no callback is passed
 * @example
 *
 * //  The example from `auto` can be rewritten as follows:
 * async.autoInject({
 *     get_data: function(callback) {
 *         // async code to get some data
 *         callback(null, 'data', 'converted to array');
 *     },
 *     make_folder: function(callback) {
 *         // async code to create a directory to store a file in
 *         // this is run at the same time as getting the data
 *         callback(null, 'folder');
 *     },
 *     write_file: function(get_data, make_folder, callback) {
 *         // once there is some data and the directory exists,
 *         // write the data to a file in the directory
 *         callback(null, 'filename');
 *     },
 *     email_link: function(write_file, callback) {
 *         // once the file is written let's email a link to it...
 *         // write_file contains the filename returned by write_file.
 *         callback(null, {'file':write_file, 'email':'user@example.com'});
 *     }
 * }, function(err, results) {
 *     console.log('err = ', err);
 *     console.log('email_link = ', results.email_link);
 * });
 *
 * // If you are using a JS minifier that mangles parameter names, `autoInject`
 * // will not work with plain functions, since the parameter names will be
 * // collapsed to a single letter identifier.  To work around this, you can
 * // explicitly specify the names of the parameters your task function needs
 * // in an array, similar to Angular.js dependency injection.
 *
 * // This still has an advantage over plain `auto`, since the results a task
 * // depends on are still spread into arguments.
 * async.autoInject({
 *     //...
 *     write_file: ['get_data', 'make_folder', function(get_data, make_folder, callback) {
 *         callback(null, 'filename');
 *     }],
 *     email_link: ['write_file', function(write_file, callback) {
 *         callback(null, {'file':write_file, 'email':'user@example.com'});
 *     }]
 *     //...
 * }, function(err, results) {
 *     console.log('err = ', err);
 *     console.log('email_link = ', results.email_link);
 * });
