Testing Instructions

Build docs without latex installed (the default Dockerfile works great)

Summary

I added a more helpful error message that informs the user that "html_only" is an option when building if they attempt to build with the default options and don't have pdflatex installed.

Output

ERROR: latex must be installed in order to create pdf documentation.
  try 'module load latex' if in anaconda
  or re-run with html_only to only build
  html documentation.

This needs to be added to the most recent release note, as this is an old fix that I forgot I did. When y'all say it looks good I can move it over and then merge it.
