Hiding attribute values that are not useful

[zachmprince]

What is the change?

In the PDF build of the docs, there are some instances of overly verbose and extremely long content that was automatically generated. These are a few of them that I found:

• List of Nuclides table. Now this is only built with the PDF
• energyGroups.GROUP_STRUCTURE
• constant.DPA_CROSS_SECTIONS
• test_customIsotopics.TestCustomIsotopics.yamlString

The last three are removed using :meta hide-value: which tells sphinx to not display the value of the attribute.

Why is the change being made?

Ongoing SQA effort

What does this do? (Sorry.) I have only seen this to hide an attribute from the docs.

Are you trying to hide the "Notes"?

This explains it better than I can:

It basically just skips rendering the default value for the attribute.
