Unzipping and managing top-level zip is working

Creating a file structure for the top-level zip (the one provided from
my courses) works as well as unzipping the files into the structure

This directory structure is made local to the scripts execution.
Currently I have a sym link set in my bin to point to this script,
    which works well for me

In addition:
- Script can handle zip's in another path (like an absolute)
- New flags added, included a flag to delete the zips after extraction
