/**
* Returns the first value in `coll` that passes an async truth test. The
* `iteratee` is applied in parallel, meaning the first iteratee to return
* `true` will fire the detect `callback` with that result. That means the
* result might not be the first item in the original `coll` (in terms of order)
* that passes the test.
* If order within the original `coll` is important, then look at
* `detectSeries`.
*
* @name detect
* @static
* @memberOf async
* @alias find
* @category Collection
* @param {Array|Object} coll - A collection to iterate over.
* @param {Function} iteratee - A truth test to apply to each item in `coll`.
* The iteratee is passed a `callback(err, truthValue)` which must be called
* with a boolean argument once it has completed. 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 the first item in the array that passes the truth test
* (iteratee) or the value `undefined` if none passed. Invoked with
* (err, result).
* @example
*
* async.detect(['file1','file2','file3'], function(filePath, callback) {
* fs.access(filePath, function(err) {
* callback(null, !err)
* });
* }, function(err, result) {
* // result now equals the first file in the list that exists
* });
