Description (include issue title and the keyword ['closes', 'fixes', 'resolves'] and issue number):

• PUMAS code now has metadata and goes through the CAM-SIMA compilation step. [Note PUMAS diagnostics will come in a later stage] - This step has been named "round3".
• This commit contains contributions from participants at the PUMAS hackathon
• Partially addresses CCPP-ize PUMAS #118
