Add MAINTAINER
Adds the section for package installs

This section adds the minimal package instals needed to get trough the
rest of the installation.
Adds a dividing line

Most of this installation is user based, allowing for users to maintain
different versions of cpan and duckpan. For starters we will mimic that
setup in our Dockerfile, however er may want to later revisit if this is
necessary/a good idea. Since Docker creates small dispensable machines
meant for rapid deployment and testing, perhaps we could move all this
to root.
Adds the rest of the installation

Adds all the rest of the installation process. Refer to the comments
before each line to see why that step is needed.
