In the original version of this article, no suggestions were done for further research. We have created this entire module by hand, with the help of prof. Los.
The information we have represented here was available to the authors at the time they wrote this article. Therefore the authors could have written this module directly themselves. At a later stage, the module could have been updated with references to later articles by Hubers, Aten; Faist & Levine, in which they lines set out in this module are explored.
