 * Computes the positions and dimensions of items that will be rendered by the list. The output from this is utilized by viewability tracker to compute the

 * Note: In future, this will also become an external dependency which means you can write your own layout manager. That will enable everyone to layout their
 * views just the way they want. Current implementation is a StaggeredList
