Adding a very basic CI test that installs through netCDF4

Issue 458: Adding initial CI

ASGS can take a long time to build everything, so this is a very short
test that makes sure that the shell can be installed via:

  ./init-asgs.sh -b -x "--update-shell"

This will generate ./asgsh and ./update-asgs.

Also adding installation checks for each step, one per script.

Resolves #458
