Full text summary of papers in Policy/Framework section

Here's an effort towards a thematic summary of the papers in the Policy/Frameworks section.  I started with summaries of each paper, then replaced those with a thematic discussion.  The original summary per papers are  in the second commit here and would remain at https://github.com/jameshowison/WSSSPE/blob/587705cb6f12f46951e822fdbf5eb72b104fa397/WSSSPE1_report/WSSSPE1_summary_report.tex
