+ * Created by Allan Wang on 2017-08-06.
+ *
+ * Collection of zip methods that aim to replicate
+ * <a href="http://reactivex.io/documentation/operators/zip.html">Reactive Zips</a>
+ * For unit returning functions
+ *
+ * Typically, the functions will execute asynchronously and call their given callbacks when finished.
+ * Once all callbacks are called, the final onFinish callback will be executed.
+ *
+ * There is also a helper zipper to wrap synchronous functions with Anko's doAsync to achieve the same results
+ *
+ * Note that not wrapping synchronous functions will render these methods useless,
+ * as you can simply define an inline callback after all functions are finished
