Model introduction

Model purpose

The file collusion_cycle.rb in app/models is used to calculate potential collusion cycles between peer reviews which means two assignment participants are accidentally assigned to review each other's assignments directly or through a so-called collusion cycle. For example, if participant A was reviewed by participant B, participant B was reviewed by participant C, participant C was reviewed by participant A and also the reviews were indeed finished, then a three nodes cycle exists. Cases including two nodes, three nodes and four nodes have been covered in collusion_cycle.rb.
