an array of event objects, each event contains:
Perform a line sweep through the faces of a graph, This method will create an array of events, each event will either "start" faces or "end" faces. In the case of degenerate faces whose vertices all lie on a line and that line is orthogonal to the sweep axis, within an epsilon, these faces will only exist inside one event and be present in both the "start" and the "end" arrays.
