| * Applies the function `iteratee` to each item in `coll`, in parallel. |
| * The `iteratee` is called with an item from the list, and a callback for when |
| * it has finished. If the `iteratee` passes an error to its `callback`, the |
| * main `callback` (for the `each` function) is immediately called with the |
| * error. |
| * |
| * Note, that since this function applies `iteratee` to each item in parallel, |
| * there is no guarantee that the iteratee functions will complete in order. |

| * @param {Array|Iterable|Object} coll - A collection to iterate over. |
| * @param {AsyncFunction} iteratee - An async function to apply to |
| * each item in `coll`. Invoked with (item, callback). |
| * The array index is not passed to the iteratee. |
| * If you need the index, use `eachOf`. |
| * @param {Function} [callback] - A callback which is called when all |
| * `iteratee` functions have finished, or an error occurs. Invoked with (err). |
| * @example |
| * |
| * // assuming openFiles is an array of file names and saveFile is a function |
| * // to save the modified contents of that file: |
| * |
| * async.each(openFiles, saveFile, function(err){ |
| * // if any of the saves produced an error, err would equal that error |
| * }); |
| * |
| * // assuming openFiles is an array of file names |
| * async.each(openFiles, function(file, callback) { |
| * |
| * // Perform operation on file here. |
| * console.log('Processing file ' + file); |
| * |
| * if( file.length > 32 ) { |
| * console.log('This file name is too long'); |
| * callback('File name too long'); |
| * } else { |
| * // Do work to process file here |
| * console.log('File processed'); |
| * callback(); |
| * } |
| * }, function(err) { |
| * // if any of the file processing produced an error, err would equal that error |
| * if( err ) { |
| * // One of the iterations produced an error. |
| * // All processing will now stop. |
| * console.log('A file failed to process'); |
