Introduce a file "HelpToUpgrade.md" which lists the changes from one version of MoReFEM to another
Currently in the Changelog I bolded the issues that may break a model after upgrading to latest MoReFEM version... but I didn't specify exactly what could break and how to fix it.
Concretely, when I applied the changes to the files I noted in a file what should be changed and used it for all the external models to update.
I realized streamlining a bit this file and sharing it in the project is a good idea; I will do so now for all upcoming releases.
