Hi Dariya, here we go, the second round. There are still a few files that have a couple more than 200 lines and there are for sure more effecient ways to wrap things into functions, but it in general it is largely reduced. I also reduced the number of steps with the exception of the decomposition. Since the code is almost identical for both health measures (DFLE and ChrDFLE), we could just present/publish the code for one of them. In this case, we can get rid of file "04b_...". Let me know if you have any problems running the code. Thanks for your review (and sorry for the sassy title, it was too late to change)!
