update: add an installation script to retrieve and setup environment modules package
already setup for the libraries installed through install_libs.sh script.

This script clone the package from GITHUB, which contains several configuration modules
designed on my personal machine, but which can be deleted (removing is easier than writing).

The script clone the package into desired directory, add suitable init script in the home
of the user (it assumes user can or does not want to write in profile.d) and make it sourced
in the standard bash profile files (.bashrc, .bash_profile, .profile).

fully operational version.

download and install:

todo: use this script to setup and install SciFor library.
