```
public SweepLineEvent(double x,
                      SweepLineEvent insertEvent)
```
    Creates a DELETE event.
    
    Parameters:
    
    x - the event location
    
    insertEvent - the corresponding INSERT event

    Events are ordered first by their x-value, and then by their eventType. Insert events are sorted before Delete events, so that items whose Insert and Delete events occur at the same x-value will be correctly handled.
