Install and load missing specified/needed packages on the fly

This is a short script to help installing packages on the fly.It is most useful if you are distributing a set of script files to people who may not be aware that the needed packages are not installed on their systems. It is also useful if you use many packages and want to organise their installation (if missing) and/or loading at the beginning of a script.
