// Instead of using [Endless Scrolling with AdapterViews and RecyclerViews]
// (https://github.com/codepath/android_guides/wiki/Endless-Scrolling-with-AdapterViews-and-RecyclerView/_edit) 
// introduced in codepath.
// There's more simple and less computational way to implement endless scrolling. You can replace 1 in if-statement 
// if(position == getItemCount() - 1) for fine tuning.
// Make use of the following code snippet in your project.
