Tidying prior to editing
Reordered authors to show properly Prasenjit's role, and to give the modellers full credit. Fixes #20. Also beefed up abstract a bit, addressing #19
Edited introduction to remove detail on SW that will come in system papers, and to re-emphasise volunteer roles
Tightened final figure discussion, strengthened conclusions and abstract: fixed #18, fixed #19, fixed #21
