* @param {Array|Iterable|Object} coll - A collection to iterate over.
* @param {AsyncFunction} iteratee - An async truth test to apply to each item
* in the collections in parallel.
* The iteratee should complete with a boolean `result` value.
* Invoked with (item, callback).
* @param {Function} [callback] - A callback which is called as soon as any
* iteratee returns `true`, or after all the iteratee functions have finished.
* Result will be either `true` or `false` depending on the values of the async
* tests. Invoked with (err, result).
* @example
*
* async.some(['file1','file2','file3'], function(filePath, callback) {
* fs.access(filePath, function(err) {
* callback(null, !err)
* });
* }, function(err, result) {
* // if result is true then at least one of the files exists
