[Nix-dev] buildFHSUserEnv and matlab impure install

[Freddy Rietdijk]

I guess the approach here is

   1. Make sure you have all the installation files offline in an archive.
   2. Prepare file for silent installation

   3. Write a Nix expression that uses `buildFHSUserEnv` and use
   `requireFile` with the name and hash of the archive
   4. Find out all the packages you need in the env
