How to build a basic Singularity container

Steps:

* shell into the container with the --writable option and tinker with

* record changes that we like in our definition file

* rebuild the container from the definition file if we break it

* rinse and repeat until we are happy with the result

* rebuild the container from the final definition file as a read-only
