New Feature: anonymize authors/affiliations from compiled PDF

[augustfly]

Include an option to expunge author/affiliations from the compiled PDF.

\documentclass[noauthors]{modern}

the noauthors option would replace the authors/affiliations block with either:

• nothing at all.
• Text that indicates that the author list was expunged

Other thoughts?

[augustfly]

Probably should also suppress the acknowledgements too.

Maybe better to call the option:

\documentclass[anonymous]{modern}
